I swage mine and pp them. I use a Corbin press and a .452 swage die to produce a round nosed bullet with a shoulder like a SWC. It has a cupped base and, pure lead, comes from the die at 480 grains.
They are patched to .459 and seated over 65 grains of FFg Goex with grease cookie (made of two 0.030" wads with 1/8" beewax between them).
I seat these by hand in unsized .45-70 cases for use in my Browning BPCR.
