I have noticed my loads with 90 to 100 gr boolits hit a bit high at 50 feet. I might work with the little 77 gr RCBS RN I use for my Colt 1903 Hammerless 32 auto. Hopefully the lighter bullet with hit lower. Too many toys not enough time. Tempted to install Crimson Trace laser grip on I frame so I can fine tune point of aim. I have also thought of adding adjustable sights to my model 31-1. It's ugly on the outside but nice where it counts. Got it for 200 on Gunbroker because someone must have stored it in a wet guncase. Lesson here is don't store your gun in a soft case.
