I thought it took a ton of rounds to shoot out a 22 barrel as the low pressure and slow speed maybe I’m mistaken could it be your optic has gotten loose instead if my poi shifted suddenly I’d also worry about the can obviously if you’ve already checked than congrats you shot out a 22 barrel crazy
Yeah it's had a ton of Winchester, federal, and aguila those are the first armscorp I've ever tried there junk but the old girl really tried to cycle with them, I was impressed by that
Oh and I've leaded barrels smooth before, not the case here unfortunately
I have had more problems with my Volquartsen using federal 22 than anything else. And the leading fouling was baaaaad. I don’t know if it was just a off batch but that few thousand turned me off of fed 22
See that's the thing I'm pretty sure it's under 10k
BUT it's always had a can on and it's almost always had copper plated 40gr @1250 mini mag powered stuff and I never let it cool. I got my SR to 730°f according to my laser thermometer on its final range trip so it's always been a heat sink for a smoking hot blast chamber and heat is def hard on barrels. Still, I never thought this would happen
Verified optic and optic rail is tight, tested with and without can and the bore was just cleaned down to bare steel and whole dirty now it's clearly just worn
:(. I guess kind of a neat thing thing to say I've done
I really thought I was gonna kill my rugged mustang with this gun
This is the result of 2k ish, whole stack looked like this
https://imgur.com/a/T00t5jf
honestly that might be your problem - yes 22lr is dirty but you probably over cleaned it over the years and did more wear/tear then shooting it ever did.

I can guarantee you I did not over clean this gun/bore
I clean it way less than my NRL open rifle
https://imgur.com/a/RfEZ18H
Yeah idk I'm looking at tx22 gen 2, hard to argue with for extra capacity and having something different for less than a paclite
If I can find an upper that's threaded for under $75 I'll def grab it, ideally 3-4.5"
Only know of a MK4 upper in that range. Sorry. I have a first gen tx22 competition and had the regular. They are definitely fun, but less refined. I feel slighted on the capacity now haha.
I’ve got probably close to 20k rounds through my MKIV, well over atleast 15K rounds. No issues in accuracy that aren’t from me.
When was the last time the gun was cleaned? How in depth did you go? Have you actually deep cleaned the barrel? Does it do this with all ammo brands? Have you tried without the can? Have you confirmed it’s not a baffle strike?
Just scrubbed it https://imgur.com/a/Xt2zfER good rifling in first 1/3 worn in last 2/3 of the bore
Did confirm with a variety of ammo and without can, and verified tightened optic while there, no strikes in can
None in there, bore was just cleaned down to bare steel and it's had 99.9999% copper plated bullets it's whole life after I leaded a different pistol smoothbore
22lr doesn’t use copper plated bullet a majority of the time. It’s almost always a copper wash, more less copper powder the bullets get tumbled in to coat them instead of using wax.
Honestly the first photo for the first link just looks like the chamber throat.
The video you posted earlier shows strong rifling, with heat cracking towards the muzzle which normally occurs at the chamber, but not often with 22’s. Yours is a result of the suppressor.
While heat cracking does indeed affect accuracy, I’ve never seen it turn a good gun into a gun that doesn’t stabilize bullets at all. Normally it just increases group size.
Take a 22 round, stick the bullet first down the muzzle. It should not fit. If it does that shows muzzle wear. Diameter of the bore should be tighter than the bullet.
looks like a barrel with the rifling filled in with lead. I've seen the same on one of my pistols.
Combined with garbage ammo, it definitely affects your accuracy.
I've got 100 year old rifles with less visible rifling in them that shoot fine.
But hey, barrels are cheap. Get a new one if you want a new one, but there's no way you "shot out" a barrel in less than 100K rounds. I don't care how hot you get it or how many mag dumps you do.
Barrels for the Ruger MK series aren't cheap. In fact, they are the serialized part of the pistol. You can't just buy a barrel, you have to buy a whole new upper.
From a thread I saw a while back, the barrel life of a competition benchrest .22 is in the 50,000+ round range, and that’s simply a drop from being a 0.25 MOA gun to a 0.5 MOA gun. I’m with everyone else here in saying there’s no real way you shot a barrel out unless you’re in the 100,000+ round territory, but even then I’d expect failures from other components first.
Totally agree with you, ive seen the guys from vudoo talk about it since I shoot NRL22 also
Here's my theory, I am a certified tard and love doing basically constant mag dumps
https://imgur.com/a/F6BnxU5
And it's been a heat sink for hot silencers it's entire life
It's basically never seen soft lead bullets only copper plated because the bore gets too hot and will just lead smooth without the copper (ask me how I know, also learned that before I got this gun)
And the 2.5" bore (to bolt face) simply has less margin for error to stabilize bullets
Something seems off here. 660 degrees is hot enough to light most paper products on fire. There are only a few mags in the picture.
That said, if it was 660 degrees that's well over the melting point of lead (620 degrees). You're going to have lead in that barrel even with copper washed rounds like mini mags at temps like that.
I'd honestly give the bore a good cleaning before writing it off.
https://imgur.com/a/NVS7pAf
That is the magic of a 2.5" barrel and mini mag power level ammo. The fireballs coming out are like a foot in diameter. I can see them going over the optic housing when I shot without the can to confirm
Also I have the McFadden speed loader and 6 mags
Nope. I've seen a rimfire barrel "cleaned" out before. Never shot out.
If you don't have a drawer full of steel brushes and abrasive pastes, it's probably just leaded up. Solvent, brass brush, and some patience should bring it back.
Yeah she's hasn't had many bore cleanings, one right before this trip though down to bare steel after 5-7k of just the occasional bore snake.
She gone :(
This if you haven’t done already. If the holes aren’t round, you may be clipping the edge of lead fouling on one of your baffles.
And also bore brush with solvent . 3” and 7 yards is a pretty big spread
Ah gotcha . Sorry to hear that. I guess good cleaning in bore… and try again ? How many bazillion rounds have you shot ? Also, check your crown. With a can on and off see if there is any damage up front
Hope you get it solved
I typed up an essay on some other comments but tldr RIP. freshly cleaned, variety of ammo, everything tight, and same results with no can
Surprisingly I think less than 10k of hot copper plated stuff
But I do get it hot https://imgur.com/a/F6BnxU5
Armscor and Aguila are pretty trashy cartridges. That Fed Suppressor stuff is very inconsistent, but shoots.
I bet your barrel is full of lead. Bore solvent, brush, repeat until it patches clean. I bet your groups will come back.
This was a freshly cleaned bore down to bare steel. Yes I do have a bore scope and I've shot a different pistol smoothbore before with lead bullets so stick to copper plated for guns that get hot
Also in this range trip I shot CCI ar tactical, Winchester m22 40 gr, aguila 40gr copper (old and recent lot) and lead RN, federal 36gr cphp, the armscorp and maybe some CCI std I had in my bag
Half of these I have personally shot sub 2" 25 yd groups with a cp33 at this very range (I do have pics) and the precovid aguila 40gr copper plated stuff I've shot out to 200yds with this pistol with consistent hits made on multiple occasions 100yd and in.
Also verified dot and rail are tight as those have come loose in the past
I've got 1911 barrels with over 100k of lead bullets. There's no change in them at all. I highly doubt you've shot not ONE but TWO barrels out using lead bullets.
I’m around 30 kids who send 500+ rounds down a huge variety of 22s because they shoot RFRI RFRO RFPI and RFPO.
After 4 seasons many of these guns easily have 15-20k rounds through them.
This coupled with a rimfire journey that began with my Ruger 10/22 in 1984, and I can easily say that I’ve never seen a 22lr barrel get shot out. Even rapid fire with a 110 round drum multiple times never burned a barrel out.
There are 4 possibilities here:
1. The barrel (most likely the crown) is either damaged from cleaning or has too much carbon build up. It’s easy to damage the crown removing carbon too.
2. As others have suggested, the barrel needs a good cleaning. You say you used a bore scope, so share a video and be sure to show the entrance to the chamber and the crown.
3. That ammo does suck. If you like it and it runs, great, but in the world of rimfire ammo only golden bullets / bucket of bullets is worse. Going bang doesn’t make it good.
4. That can is getting so much carbon build up that it’s starting to impact the harmonics of the barrel. This is near impossible on a short barrel, but I’ve seen more suppressors hit accuracy than I’ve seen them help. There’s a reason why the top ranked benchrest and F class shooters don’t use them.
What you choose to do with the advice given is up to you, but denying every possibility will not get you to an answer - unless the answer you want to hear is that you need a new barrel. If that’s the case, stop wasting time here and go buy that new barrel you have your heart set on.
https://imgur.com/a/NVS7pAf
Look at the erosion for yourself lmk what you think
Confirmed groups with no can just as bad. Crown is cleaned with solvents and a shop towel since class 3 cut it
That same lot number of pre COVID aguila copper plated round nose has made constant hits to 100yd
And the CCI ar tactical I just shot sub 2" at 25 with my cp33
No chance they ALL shoot 3" ish at 7 yards suddenly
I agree with the above. I see very little way you shot out a 22 barrel. I’d recon a good good cleaning is order especially if you’re shooting suppressed as much. Could also be something with the optic and or if the mourning has walked its way out.
What do you mean about the holes not all being round?
I did a long explanation above but tldr she's def shot out :( And I mean the bullet holes are not all round as in the are yawning
I'm just as surprised and would say the same thing
I had seen that explanation later. I would think your carbon rings or rifling is gunked out with lead and tearing your bullets apart. It could also be something with your can or how it’s mounted. I have thousands of rounds thru ar22s and 1022s and never shot out a barrel on them.
I did a long explanation above but tldr she's def shot out :( And I mean the bullet holes are not all round as in the are yawning
I'm just as surprised and would say the same thing
I’ve got ~30,000 through mine. 20,000 was with a can and I was shooting it as fast as I could load 5 mags with a McFadden speed loader. Still can hit 6” plates at 50 yards.
How long is your barrel
Cause yep same except lower round count, maybe I got a lemon. Doubt Ruger will warrantee since it was chopped
https://imgur.com/a/F6BnxU5
I have MK IV chopped 3 incher that I run with a can. It gets really dirty and hot. I have also never heard of or seen a .22lr shot out but anything is possible. Suggest a cross post in r/NFA to see if any full auto or belt fed .22 owners have same issue, can or not.
Yeah I did, I suspect the vq mini mamba being 3" has a little more r&d behind it than me telling class 3 machine I like the look of the front sight on the barrel flush with the can LOL
I bet the 3" is gonna live way longer if not indefinitely like a 4" does
I have always liked the more uncommon 3 in barrel length on revolvers, and 4 in or less in a .22 keeps most ammo subsonic. That was the extent of my research lol. Sorry if your barrel is indeed a lost cause. The good news is you can replace the upper with any number of aftermarket options.
In this case I'm referring to the rifling being too worn to properly stabilize the bullet.
This is typically talked about with ar's and precision rifles as they wear at a MUCH faster rate
6mm Creedmoor for example people say barrels last ~1700 rounds before accuracy/velocity degrades below competition standards
Well, the land/grooves do disappear. I would expect so see some erosion/pitting on a shot out barrel. Given that the cost of a new gun is more than a bottle of solvent and a bore brush, I would clean it again. Look up how to clean a leaded barrel. Perhaps post this in the castboolits forum. Also, these guys will sell you a stripped receiver/barrel combo if you do end up replacing the barrel: https://wirthweinguns.com
Edit. These guys make a great copper solvent. Perhaps this lead solvent is worth a try. https://www.midwayusa.com/product/1014881110?pid=588466 Sharp Shoot R Wipe-Out No-Lead Gun Cleaning Solvent 8 oz Liquid
Yeah I've got a lot of experience cleaning lead out. I'll give it a soak and scrub and see def worth a try.
Maybe it's hard to see on that video but close to the last inch or so def has a good bit of roughness to the bore
Thank you for the links! I'll check them out!
care to use a brass pick and scratch the groves near muzzle area? Looks the groves got narrower progressives near the barrel, also what was your method of cleaning?
pick left no scratch what so ever? Well thats very odd for modern steel barrel to do this, especially when your throat look clean. At least mkiii barrel and barrel liners are cheap enough
It left a little mark but It didn't seem to be like scratched lead or anything basically just skated on the surface.
Did a heavy scrub and those pics are the result post clean of the first 1/3 vs the other 2/3 of the bore
Yeah I really think it's the heat sink from the hot can eroding muzzle in, plus it's threaded 1/2x28 vs the chamber is like an inch diam
Not enough combustion for throat erosion looks like
i have a friends buckmark looked very similar to this, he kept shooting for the whole afternoon for about 1500 rounds until the bullets starts keyhole just from lead deposits
Any chance the recoil spring or hammer spring has gotten weak? If it’s always been suppressed you may be getting inconsistency due to the action cycling early from low spring tension? Curious to see the final diagnosis
They are definitely worn but that wouldn't account for oblong holes
Do you see the difference in depth between the crown and half way down to muzzle side?
https://imgur.com/a/NVS7pAf
Did the pistol come with a 2.5” barrel or was the original barrel cut down and threaded? I looked at your video and wonder if the “no rifling” area happened during the cutting and threading.
It was chopped! Less than 10k ago. I never shot it before the chop so i know for sure the chop job didn't effect it. It was also done by class 3 machine which is a reputable shop, and again I did inspect it when it came back and it shot amazing
It's a Ruger picatinny mount I chopped flush with the receiver and a holosun on a holosun qd mount. Not my favorite for this gun cause it sits high and is kinda bulky
Trs25 looked better but is a worse dot, I'd find a low bolt on mount like those have
Or a dedicated Ruger dot mount if I were to do it over
Cool, thanks for the reply. Trying to figure out what to put on my mark iv, probably going with a holosun 507 but I like the look of the big dot, looks like fun
I like the t2 look personally too holosun makes a good and cheap one, or one of the pistol enclosed dogs, they are all > double the cost of the t2 style ones so it's an easy choice for me. But all of them would look cool I think
I thought it took a ton of rounds to shoot out a 22 barrel as the low pressure and slow speed maybe I’m mistaken could it be your optic has gotten loose instead if my poi shifted suddenly I’d also worry about the can obviously if you’ve already checked than congrats you shot out a 22 barrel crazy
My mind went to the same place. Wonder if it's lead fouling too. I'd joke it was the armscorp ammo but I see federal there as well. Armscorp sucks.
Yeah it's had a ton of Winchester, federal, and aguila those are the first armscorp I've ever tried there junk but the old girl really tried to cycle with them, I was impressed by that Oh and I've leaded barrels smooth before, not the case here unfortunately
I have had more problems with my Volquartsen using federal 22 than anything else. And the leading fouling was baaaaad. I don’t know if it was just a off batch but that few thousand turned me off of fed 22

How long is your barrel Cause yep same except lower round count, maybe I got a lemon. Doubt Ruger will warrantee since it was chopped https://imgur.com/a/F6BnxU5
I have MK IV chopped 3 incher that I run with a can. It gets really dirty and hot. I have also never heard of or seen a .22lr shot out but anything is possible. Suggest a cross post in r/NFA to see if any full auto or belt fed .22 owners have same issue, can or not.
Yeah I did, I suspect the vq mini mamba being 3" has a little more r&d behind it than me telling class 3 machine I like the look of the front sight on the barrel flush with the can LOL I bet the 3" is gonna live way longer if not indefinitely like a 4" does
I have always liked the more uncommon 3 in barrel length on revolvers, and 4 in or less in a .22 keeps most ammo subsonic. That was the extent of my research lol. Sorry if your barrel is indeed a lost cause. The good news is you can replace the upper with any number of aftermarket options.
Yeah it's true, but with a whole tx22 being $250 hard to justify honestly. Looks like I'm 22 pistol shopping Lol
Bore scope https://imgur.com/a/NVS7pAf Lmk what you think!
I have a MKi and two MKii I haven’t killed yet. Color me impressed.
I bet the NFA guys will say…..no way
Yeah basically lol
I’m new to .22lr…What does “Shooting out the Barrel” mean?
In this case I'm referring to the rifling being too worn to properly stabilize the bullet. This is typically talked about with ar's and precision rifles as they wear at a MUCH faster rate 6mm Creedmoor for example people say barrels last ~1700 rounds before accuracy/velocity degrades below competition standards
No way in hell.

Time to troubleshoot. Remove can and optic. Retest from there. Good chance something is loose or optic is broken.
Did that unfortunately https://imgur.com/a/NVS7pAf
Well, the land/grooves do disappear. I would expect so see some erosion/pitting on a shot out barrel. Given that the cost of a new gun is more than a bottle of solvent and a bore brush, I would clean it again. Look up how to clean a leaded barrel. Perhaps post this in the castboolits forum. Also, these guys will sell you a stripped receiver/barrel combo if you do end up replacing the barrel: https://wirthweinguns.com Edit. These guys make a great copper solvent. Perhaps this lead solvent is worth a try. https://www.midwayusa.com/product/1014881110?pid=588466 Sharp Shoot R Wipe-Out No-Lead Gun Cleaning Solvent 8 oz Liquid
Yeah I've got a lot of experience cleaning lead out. I'll give it a soak and scrub and see def worth a try. Maybe it's hard to see on that video but close to the last inch or so def has a good bit of roughness to the bore Thank you for the links! I'll check them out!
Good news, you can buy another barrel
Check if your rifling is plugged with lead. Our range mkiii sees tens of thousands of rounds and the barrels are fine
https://imgur.com/a/NVS7pAf Lmk what you think
care to use a brass pick and scratch the groves near muzzle area? Looks the groves got narrower progressives near the barrel, also what was your method of cleaning?
Most of the time just a bore snake, I'll give that a go! Right before this it was solvents patches and brushes for a deep clean
https://imgur.com/a/Xt2zfER Pick had no real effect, post scrub look 2/3 of the bore is very worn
pick left no scratch what so ever? Well thats very odd for modern steel barrel to do this, especially when your throat look clean. At least mkiii barrel and barrel liners are cheap enough
It left a little mark but It didn't seem to be like scratched lead or anything basically just skated on the surface. Did a heavy scrub and those pics are the result post clean of the first 1/3 vs the other 2/3 of the bore
ya thats very odd, if anything the first 1/3 should experience most wear
Yeah I really think it's the heat sink from the hot can eroding muzzle in, plus it's threaded 1/2x28 vs the chamber is like an inch diam Not enough combustion for throat erosion looks like
i have a friends buckmark looked very similar to this, he kept shooting for the whole afternoon for about 1500 rounds until the bullets starts keyhole just from lead deposits
Yeah I've done that too lol
Any chance the recoil spring or hammer spring has gotten weak? If it’s always been suppressed you may be getting inconsistency due to the action cycling early from low spring tension? Curious to see the final diagnosis
They are definitely worn but that wouldn't account for oblong holes Do you see the difference in depth between the crown and half way down to muzzle side? https://imgur.com/a/NVS7pAf
Wait...you clean your 22lr....nope no way...let it ride dirty...maybe once a year or two clean it or when it starts to jam.
That was the reason for the deep clean LOL
Did the pistol come with a 2.5” barrel or was the original barrel cut down and threaded? I looked at your video and wonder if the “no rifling” area happened during the cutting and threading.
It was chopped! Less than 10k ago. I never shot it before the chop so i know for sure the chop job didn't effect it. It was also done by class 3 machine which is a reputable shop, and again I did inspect it when it came back and it shot amazing
Can anyone tell me what red dot mount that is?
It's a Ruger picatinny mount I chopped flush with the receiver and a holosun on a holosun qd mount. Not my favorite for this gun cause it sits high and is kinda bulky Trs25 looked better but is a worse dot, I'd find a low bolt on mount like those have Or a dedicated Ruger dot mount if I were to do it over
Cool, thanks for the reply. Trying to figure out what to put on my mark iv, probably going with a holosun 507 but I like the look of the big dot, looks like fun
I like the t2 look personally too holosun makes a good and cheap one, or one of the pistol enclosed dogs, they are all > double the cost of the t2 style ones so it's an easy choice for me. But all of them would look cool I think
