If I ever get this .430-310-rf lee 6 cavity mould casting a.430 boolit Im going to need a gas check . all the sizing dies/gas check crimper are .429.so how do you put a gas check on a .432 boolit ? I say a.432 boolit because my ruger sbh requires it and I wont quit because I know it will be done.I have cast a couple hundred boolits with this new mould thinking it needs breaking in. still same size..428 .I could'nt wait to shoot some .they fell into the resized case.not good.Im cooking acww/3% tin. this is my first mould .so I thank you for any help.
