I have been playing with a RCBS 35-200-FN 35 Caliber (358 Diameter) 200 Grain Flat Nose Gas Check boolit for a couple of years in my model 8 and 81 remington. I have had decent success with 26gr. of IMR4198 groups are about 2 1/2 to 2in. at 90yds off a bench with open sights. these guns shoot 1in with jackets. dose anyone have a better boolit powder combo? my bores are 358 I am sizing to 360,,,,,,,,,,thanks
