My load, work up to it! A 440 WFN with 50 grs. of H-322. Clocks 1800 fps. out of an 1895G guide gun. This a hand cast wheel weight bullet with Lyman Moly lube. This does not lead at all that I can see. I have shot CP's bullets to almost 1400 fps. with no leading problems. If the extra speed causes difficulties, cast your own!. This load shoots around 1/2" at 50 yds., I have shot a Russian boar with a WFN out of a .475 at 1350 fps. and the visible internal damage was notably greater than any of the jacketed bullet boars shot the same weekend. Not much of a test, but the damage from a non-expanding WFN bullet was impressive! Good luck.
