to crimp or not to crimp?
I've run them w/no crimp at all & i've crimped the snot out of them, both on advice of others.
I prefer the slightest crimp, just a bit of a taper, hard to see w/the naked eye... but a gs friend said i'll pull tighter groups if i add a good solid crimp... i've had others say the opposite...
I'm casting these mostly... 230gr 0 ogive...
This is the heavy crimp... and they do make nice groups, but the reason i ask is because with the crimp the JHP let's the boolit enter the rifling pretty solidly, which might help, i dunno, but it does make it tough (bordering on impossible) to eject by hand...
so... i hear varying things from friends & forums, whats the official HPFF stance on crimping .45ACP guys?
