RE: .44 ammo
I picked up a box of Leverevolution 44 mags the other day and my Model 94 rifle likes em! I didn't nail it down to a bench or anything, but leaning over my truck bedshooting 50 yards with open sights I was getting 3" groups.
I'd like to get a bench and see what it will do. I haven't tried them yet in my Super Blackhawk.
