I'm looking for a good .357 mag SD round for my S&W 640. I've tried the Hornady Critical Defense .357 mag load and it seems pretty good. I didn't mind the recoil and was able to be accurate with it. I currently carry and like the GDSB .38 +p in my S&W 638. I know that there is a GDSB .357 mag round, so that is a possibility. From my research it seems the Golden Sabers and Silvertips have a good following as well, though they were not necessarily designed for short barrels.
However, I have come across the BB load that is low flash/low recoil yet still a powerful .357 mag load. It comes in 158, 140 (out of stock) and 125 grain loads. Does anyone have experience with any of these loads and would like to comment? The write-up about this ammo on the BB web site indicates this is a very well-planned load, but I'd like to hear some less partial opinions.
Thanks for any responses!
