I just picked up a mint S&W 640-1 Pro Series .357 mag. It has the 2.5" barrel and dovetailed front and rear night sights, and is cut for moon clips which I have. I'm looking for a moderate, non- bone-rending load shooting my Lyman 358156 HP GC boolits cast from 1:20 lubed with LLA. I have Unique, 2400, 231, Titegroup, Red Dot, HS-6 and CFE Pistol to play with. All advice will be appreciated. GF
