In my Model Six Remington, a VERY nice accurate load is a 170 Rem RNSPCL over 46 gr IMR 4064 in neck sized Federal cases CCI 200 primer OAL 3.19( yes its alot of shank sticking out of the case...) Chrono'd velocity 2380 fps and consistent groups of 1 1/4 inch or less at 100 yards. One group center to center was 5/16th inch for 3 at 100 yards. Nice deer load and its easy on the shoulder too!
