I recently purchased a Rock Island Armory M200 pistol with a 4" shrouded under lug barrel. I use to reload for my S&W Mod 10 4" heavy barrel revolver. The model 1 0 is +P rated. The M200 is not +P rated but can be fired with +P occasionally, just not a steady diet of them. My granddaughter now has my Smith, therefore i bought this one. I have Hornady 158 LSWC's, Hornady 148 LHBWC's, and some new cast 148 LHBWC's and Titegroup and HP-38 powders. I am just looking for someone who has experience loading for this pistol and these bullets. This will be my in the field, in the glove box, in the tackle box, and in the night stand revolver. Leaning toward LHBWC as defensive rounds. Any suggestions are appreciated and guidance is always
