Ammo types and the semi auto Bren

[AmEngRifles]

Thank you all for your responses.

BAR, that is a reassuring if not timely information. I will now proceed to use up my WWII era ammo and enjoy it. I should hope that split necks do not lead to burst barrels?

Snafu22, as far as I can tell, my gas block is not drilled larger. It has run fine on setting #3, since modifying the return and striker springs a bit. I do not know Project Guns history or approach on Bren builds. All I know is the one example I own. I do know Len at Historic Arms does drill gas cylinders, as my MkI has a unit with drilled holes.


Action Yobbo, I WISH my Brens ran on Wolff or PPU. I had this same issue with a Historic Arms Bren and even visited Len over the gun's functioning. He blasts those makers for his Bren builds. Says the casings are too thin. I tend to believe him, as he cut some in half to illustrate. Even with barrels in spec and head space, I still get case head separations with those commercial types of ammo all the time. Count your blessings if your gun runs fine on them. Most current commercial makers are not making war time ammo, for Vickers, Brens and Lee Enfields. They are making ammo for the Lee Enfield only, pretty much.

I am limited to HXP, MEN, and mostly any British, South African or Commonwealth made military contract .303 for the semi auto action. I have avoided using the older WWII era ammo, as I have to do the "double clean"...hot, soapy water, then dry and use modern bore solvent then oil the whole thing down. I hate rust.
