So Jim from backfire says it's impossible to shoot a sub moa group into a sub moa target... Like wtf here's 4 and I haven't even worked up the powder charge yet..

How many shots in each ?

So turned the necks on 100 pieces of new Alpha brass down to 11 thou for my chamber, just to realize after I neck them down to 22bra the thickness is now 12.2 thou.. it still chambers with a loaded round but there is only like 1 thou clearance total may e less.. my Smith says send it.. what do you guys think?

Hey guys so I'm trying to troubleshoot an issue, when fire forming new Alpha 6bra brass to 22bra I have been doing the false shoulder method so that there is always a good lockup on the bolt. I recently did 25 pieces and had no issues with firing. However in the picture you can see 1 had a pierced primer and al.ost all of them have a mark from the ejector. My load was 26.8 of Varget and the avg across all 25 pieces was 2880. I've pushed this cartridge to 3100 before so it seems weird that I'm seeing this but maybe that is still too hot for the 1st firing since my headspace does move .010. what do you think

Have you fire formed a lot of brass with the barrel? I've had barrels do that after jamming a few hundred false shoulders. In my case I think the neck shoulder junction was rounding out with use and the crush fit was becoming loose.

No this was the first batch I have done. I will say I rewatched Greg from primal rights video on it again. And I never took my ejector out to check fitment of the false shoulder I always checked it with it left in which I wanna re do now
