Bren newbie: Rimlock woes

[Peter Laidler]

Hey................... DANGEROUS PRACTICE! Never but NEVER cycle rounds through a Bren unless they are DRILL or Armourers dummy rounds. It fires the moment full locking is complete.

I'm away from home and won't be back until Friday. I should have pictures and a shooting report by next week. Thank you for your continued interest to help.

My bad, I should have clarified with 'Drill rounds'. Assumption is the mother of all f**k ups as they say.

I traded ammo to a friend and he gave me a mix of three different kinds of factory surplus ammo. As some of you may have suspected my reloads were the problem. I was using hornady 174 grain FMJ projectiles that I crimped low on the ogive. This results in a shorter OAL than the military ammo which then allows the rounds to move within the magazine and rim lock the gun.

It was a great day on the range. Thank you all that took the time to help me.

Happy shooting.
