Once the crimp is gone, that ring of blue plastic slides right out, and the cartridge is ready for a bullet.Īt this point, to decide what I was gonna shove in there, I had to do some serious thinking about pressure, so here's what I thought: This gives room to expand the case mouth - just enough to remove the crimp. Turns out, the best thing is to break off and discard the part outside the case, then the rest will easily push down to the overpowder wad.

There's a lot of talk about "wouldn't it be nice", and lately there's the 45-grain stuff from Winchester Australia, finally being introduced here, though it's still exactly equivalent to 45-grain subsonic.
