38 cal. RNFP 158 gr. .358"
This works well in the lever guns. Seat it to whatever length works for your gun and crimp into the lead. The nose shape is identical to the 125 gr. RNFP so we put a tiny dot in the nose so you can tell them apart after they've been loaded. A lot of cowboy shooters don't change their powder charge and just drop in one bullet or another and the length remains the same. They can do this because their loads are already low pressure loads.
