Just took my new 640 Pro to the range. Great gun. I fired some .38 spl, some .357 Golden Saber, and 158 gr PPU .357. The Golden Sabers were very nice to shoot, the PPU ok but with the increased recoil, I wouldn't want to spend a day shooting them. Is there a magnum range ammo at a decent price that will recoil more like the Golden Saber than the PPU? Anyone have experience with recoil from Geco 158 gr magnums? I know I can use .38 spl, but the magnums seemed more accurate to me. This being my 1st .357, is it hard to clean the cylinder ring the 38's leave in the cylinder? That's one of my reasons for looking for a mild magnum range load. I don't reload so I could use any help I can get. Thanks.
