Since I started talking about culling brass, a lot of you have started talking about culling brass. Just remember that things aren't always so cut and dried.
Here are two separate 10-shot groups I just fired back to back using culled brass. This is on a whistle clean barrel. Had 3 rounds come out... but otherwise this brass that I had set aside for throwing flyers on the previous firing was absolutely hammering on a 20rnd string of fire.
What changed? New box of bullets.
I ran out of the 1000 bergers I had and tore into a new 1000.
The quest continues.
1/4 MOA Fouling shots!
