I'm gaining new respect for lead. My ML benchrest rifle uses a 2 piece bullet. The nose is cast of 20:1 and the base is pure lead. The halves are swaged together to form the final bullet. The bullet is 2 strip paper patched and force fed thru a false muzzle system.
In order to swage the bullets I was told to whack the punch with a hammer. After doing that a few times I figured there had to be a better way. The swage body and base with the punch will not fit in a reloading press so I tried my friends 20 ton hydraulic press. Granted, the press is getting old but I pump on it till the cylinder stops moving and the fluid starts to by pass. And that is not excessive pressure on the bullet. I'm just starting to get flashing around the base of the bullet and the punch face. Gonna make a better fitting punch. This makes a good bullet. My point is the 20 ton press is not overkill. Also the 3lb hammer and 3 good whacks accomplished the same thing, just hard on the dies and punch. It takes a lot to make lead move. Also makes you wonder how much pressure the RCBS Rockchucker produces.
