Has anyone tried these new deeper 30 caliber gas checks yet?
I've been trying gas check bullets in 327 federal, and having mixed results. With plain base, I'll get shots spread rather evenly, and have shot some rather nice groups. With gas check bullets, I have a .284" shank, and I'm using Sage's standard copper 30 caliber checks, and sizing to .314". The first thing I noticed was the gas checks do not seem to crimp on very tight, and I could pull them off by hand if I wanted. On target, I'll get some holes touching, but lots and lots of flyers. I have to think some gas checks are falling off and causing them. I have yet to have a gas check bullet perform better than plain base. I am going to try annealing the checks I have, but also noticed the new and deeper gas checks. I am wondering if these will stay on better. The gas check shank is long enough to accept them.
