Help with Remington 788 .308 extraction

[wild03]

Hello all, thanks in advance.

 

I bought the rifle on a state sale from a widow, the rifle looks in great condition, have not been used in a long time, the lube on the trigger was hardened and trigger didn't function. cleaned it all up and it shoots well with the ammo I also bought from the lady. old winchester silvertip 180gr

Issues started when i bought a bulk 7.62 PPU ammo, seems like every other round gets stuck on the barrel after firing. it is impossible to pull the bolt back, I have to use a cleaning rod down the barrel and tap the case out. going back to 308 no issues. but the PPU keeps doing the same thing,

What could be causing this?

Thanks

7'62 has thicker brass, maybe the barrel is a dedicated 308 barrel. it should be stamped on the top or side of the barrel. most hunting rifles are 308 barrels since military stuff is FMJ and not legal to hunt with in most states.

Barrel only mentions 308 WIN, but read online that you can fire both. but that a 7..62 should not fire 308

Many rifles can use either 308 or 7.62x51.  Yours may be an exception.  If it shoots 308, I would stick with that.

You could also try other brands to see if it is only the PPU that it doesn't like.
