Semi-auto Bren piercing primers - any solutions?

[dcollector]

Thanks Jim, this was 100% new manufacture factory Seller & Bellot ammo.

Yes, I posted in several forums on this question, as I really don't want to damage the Bren, apparently you are correct S&B are hot loads with weak primers.
I'm going to run some WWII Brit through it, and some PPU next week, heat that old barrel up and see what happens.

Thanks.
