Trouble is buying store bought they are probably cast too hard.
Bronko, a little while ago I sent an e-mail to Hornady asking for the Brinnel hardness level of the Frontier line of cold swaged lead bullets. I load the Frontier .314/90 grain semi-wadcutters for light plinking loads in a .32 Mag handgun. They seem to be pretty soft and are pin-point accurate in my little revolver.
I often thought of trying .451 bullets out of my GM LRH 45 barrel.
Hornady has .452 and .454 bullets in the Frontier line, but no .451s. I don't know how the .452s would fit. See them here.

I had thought about going with the .45s for my little project. But the heaviest .452 is 230 grains and has a round nose profile, which is not what I want. The .454/255 grain flat point looks pretty darn good, but I decided to go with the .430 because it would give me the option of both a Semi Wad Cutter or SWC Hollow Point in 240 grain.
