so did some figuring on using the Lee C309-185 boolit in my 30-30 and be able to have the crimp grove at the end of the case.
the standard 30-30 case is 2.039" long
now to seat the bullet deep enough to keep it off the rifling i need to trim the case back to 1.900" to have it at the crimp grove
would taking .139" off the case length be ok to seat the bullet deep enough into the 30-30 case with the case neck end at the crimp grove be ok?
the bullet will end up being a bit past the neck and into the larger portion of the case but i also noticed this bullet will be that way in 30-06 and other cases. would this cause issues for me? i think in the 30-30 the gas check would be a tad past the neck if this makes sense.
