Looking for those with experience with H4831 in the Win. 50 Express in the Model 1886. I’ve had good service with a full compressed load under a cast 345 gr. FN. with a Federal Large Mag Rifle primer. has anyone else here been using this powder in their 1886 .50?
No Sir, but RL-15 will easily take you from mild to wild with hard cast bullets up to 700 grains if your barrel has the twist, my '86 50 cal wears a 20 twist McGowen barrel.
