My first 6BRA arrives tomorrow

Ok..so increasing pin fall gives the pin more striking power against the primer because it’s being cocked further back?? But pin protrusion stays the same?

Yessir!

My ackley Swede had 4 misfires on lapua brass using cream of wheat. All four brass measured short. Tight neck and .020 jam on a bullet got it done.

The target on the bench looked good! Keep us updated.

@Nature Boy

Did you get a chance to pull your bullets? Or get anything figured out? I am interested to see what happened/fixes your issue.

Or load them to jam instead of jump?

I have to jam my BRA to +.020 when fireforming and still get a few ftf's, drop the pin on them 3 times nothing, take them out then rechambered and they went.

I’ve been out of town all week. I’ll have some info when I get to the range this weekend

Update

I beat the bullets out of the 22 rounds that didn’t fire (all had powder, as I knew they would) and loaded 10 back up with the same load, including the #450 primers, but jammed the bullets 0.010 into the lands this time.

On the second go round 2 out of 10 failed to ignite. 20% is an improvement over 44%, but not good enough to use them for fire forming. I loaded more fire forming rounds with Fed 205m, CCI #400 and Rem 7 1/2 primers and all 30 of these fired.

I’ll try the #450s again with fire formed brass and see if the issue with these persists

I’ve found that the 450s have 100% strike rate after cases are ff..

I used the Fed GM205M yesterday doing my 1st ladder at 300yds with a BRA with H4895 103VT's 15in. 30.1 to 30.5 44fps ES and all 5 shots stayed in just over 1/2" in a light breeze with 1/4" vert. I still have to play with seating and the Ezelle tuner. That will be done next weekend at Williamsport. What i am getting at is the Fed primers will be fine if they are going BANG for you.

Regards
Rick

ps: I FFed 100 pieces with the mentioned primers and all went BANG......
