Went to the range today with my first few 2400 loads. Missouri 158g coated LSWCs.
Some 38Sp. These had enough recoil in the steel 60 that I know I could never shoot them in anything lighter. Left a little haze in the barrel but not too bad. These had a moderate crimp and the fifth one lengthened about .005" over four shots.
Some 13.5g 357, characterized by Skeeter as "medium" and by me as "Ow!" Heavy crimp and no pull at all. And... barrel was clean as a whistle afterwards!
Big flash and bang, more than Power Pistol.
Primary lesson learned: I need a 686.
