okay, I am going to mill out my .22 bator mold tomorrow to between 70-80gr from 55gr. at first I thought this would be super easy, my wife being a hygienist can "borrow" really nice specific shanks for me from work, and I found a great one, with the size and perfect shape I would like. and being medical devices, they are about as true as you can get
so, I assumd I would just get the mold clamped in correctly on the mill and set up the stops to go to the desired length and use this shank to drill out the grease ring and crimp ring and lengthen the nose. and then polish the internals to a fine shine. BUT.....this ain't gonna work, I need that gas-check shank. so how on earth do I expand the internal size of the mold w/o cutting through the check shank? any ideas? has anyone done something similar?
after running the new .227 sizethough the .225 sizing die, I should have a great bore riding surface left-over
my only idea, is to chuck up the end-mill shank and take a file and grind down the fat body of the die to a point on the nose that is the .208-.210 I need for the check and just lengthen the nose. I don't know of a way to do just one side at a time and kep it true enough, how does lee do it?
