I use the 240 and 210 Lyman, hard cast SWC bullets with Unique. The 210s are very accurate with 12 gr at 200 meters and is my load for Cowboy Silhouette. The 12 grain Unique load takes 70 pound T-1 armor plate rams. My Marlin in a 1969 production rifle, straight stock, without the pistol grip. It has the early micro groove rifling. I found that hard cast bullets hold the lands sized to the groove diameter, I use LBT Blue lube. I put a 2x old steel tube US made Bushnell scope on a tip off mount.
