Mild .357 handload advice needed
I'm trying to find a load for my SP101 that will be somewhat more powerful than a 38+P load, but less than a full power .357 load, using Speer 135 GR short barrel bullets. A little arthritis in my hands has made full power .357's painful to shoot, though 38+P doesn't bother me.
According to my Speer loading book, starting powder weights for .357 produce 2-300 FPS more than max 38+p loads. I know that using less than starting powder charges can be dangerous in rifles, but would that matter in this case? I have several different powders on hand, including W 296, Unique, and blue dot. I would be using .357 cases, not trying to load 38 cases above recomended charges.
