Went out and did some shooting with the 5" John Ross .500 Mag today with cast bullets from the Mihec "Alley Cleaner". With the pentapoint version mine are coming out at 450 grains. Even though being nearly a wadcutter it shot well and flatter than I expected to around 300 yards at a dirt bank. Velocity was an easy 1000 F.P.S. chronographed. Next will be some BL-C2 pushing up to 1200 F.P.S. I realize this is far below the guns potential but will easily outmatch for now my potential. Anyone else?
