I spoke to the owner of Rim Rock Bullets about a year ago before I ordered a bunch of the bullets. He told me the 158 gr. LSWCHP-GC they sell to the public is exactly the same bullet as they provide to Buffalo Bore for their +P loading. He told me Rim Rock uses a 30 to 1 mixture of lead to tin (which makes it 97% lead and 3% tin). That mixture appears in an old Lyman manual I have as a recognized mixture and makes about as soft an alloy as one can cast, short of pure lead.

I load mine over 8.0 gr. HS-6 and a mag primer in a Winchester Nickeled 38 Special +P case to duplicate the Buffalo Bore +P load. Found that load on this forum.
