I am using a MP 359-640 Mold with Round Pins. Shot out of my 3" Revolver, Average over the Chronograph is 1265fps. Shooting these into water jugs I have used both ACWW+2%SN and AC 50/50 (WW/Pipe)+2%SN with the same results. First Jug just explodes apart, second jug is ripped up also and laying in the 4th jug is the bullet. As you can see the Nose is gone. Which way should I go with my alloy to keep these Together?
