I have a Leeth adjustable P.P. mould that throws a flat-nosed slightly tapered bullet for .40 P.P. I am making a reloading-press type swage die to reform nose to a slightly smaller flat nosed meplat but with a more radiused nose shape to duplicate original factory round..and to eliminate taper to a parallel sided slug of .398" dia. Bullet metal is soft 30-1 pure lead/tin alloy. I have yet to make up form tool..half reamer. My question is, since these half reamers don't cut very well at end, unless there is a pilot hole, I wonder if I could get away with leaving a small .060" to .125" hole thru nose..to use for ejector punch..but not have punch present while swaging..it would save drilling c' bore to back up punch & trimming punch face to match meplat surface? Just wondering for the minimal swaging pressure..any extrusion into hole would be flattened by ejector punch when removing bullet? Thanks!
