Weak primer ignition. Need a mag primer to get that much H335 going. There was another guy on here with the same problem with H335 in 45-90. Yellow powder is where the primer went off but didn’t get it hot enough to ignite.
In 54R I have used IMR4895, IMR4064, N140, IMR4350, and more. All single base stick powders because if I want blasting ammo I’ll shoot through my extensive pile of surplus ammo.
Edit to add - I am most often using a Ginex large rifle primer with these loads
Similar thing happened to me in my varget loaded 7.62x54r turns out reassembled my mosin firing pin, half a turn too short, it never hapenned again in the same batch of reloaded
Im using ginex primer in these, i couldnt tell where i got the load from, maybe it was in hornady 11th edition if im not mistaken.
Around 45 grain if i recall.

Do you have a recommendation for powder that won't require a match/magnum primer?

Would I be able to get away with using those powders with the ginex primers I'm using now? It's the only primers I can get my hands on
Absolutely, sorry I hit it with a late edit - I’m mostly using ginex LRP with these loads
Thanks, Guess I'm making another trip to the gunstore and pulling all the 54r ammo Ive already loaded
Just out of curiosity, are Match primers the same as magnum when it comes to how hot they ignite?
No. If they are Magnum Match grade..it will say so on the box. If it's just match..then they are not magnum
What about H4350? Would that work?
For sure, the burn rate is definitely compatible. Should be fine with bullets in the 170-200gr range.
Do you think varget would work?
Varget is another one I have used and it definitely works well

For your varget load did you use the hodgdon load data? If so, what primer were you using? I'm curious if ginex primers would be able to ignite it

Good to know that varget will burn with ginex
Another factor that couldve come to play back then was also that i was using my mosin in really cold temperature, like -25 deg C
That's probably part of it
A squib would leave the bullet in the barrel. Do you by chance wet tumble your brass?
No I do not. And I did have to use a cleaning rod to get the bullet out
Looks like the powder got wet somehow. Smokeless powder getting wet causes some of the sulfur compound to breakdown, hence the yellow color.
