It will fit your gun, because I cut every mold to customer specs. Tell me what you want for nose length (crimp to nose tip) and diameter and I make it. Any kind of base. 475 gas checks are available from Bullet Swaging Supply, and allow you to drive that bullet to drive that bullet to 3000 fps in a rifle, if you use LBT lube. BFR revolvers are strong but it would be wise to hold the speed down some for that though.
The above flexibility is true for any gun from 22 cal up to 8 bore. I make molds for all of them.
