Sorry James, I thought you were talking about pistol loads. Rifle loads are even more tricky as you have found. The most successful rifle cast bullets I ever used were the SAECO RG-4, about 195 gr, lubed with the NRA ALOX formula (50% pure beeswax, 50% ALOX) and crimp on Hornady gas checks. Redding still stocks this bullet mould (#301, 196 gr TCGC). In fact, I probably still have my original SAECO mould, purchased after several conversations with Bob Modisette, owner of the company. You might also try bullet mould #307, FPGC. I didn't have a chrono when shooting the original RG-4 bullets so many years ago but estimated my loads using medium burning rate rifle powders at about 1800-1900 fps. Some other cast rifle bullets were totally useless and would even keyhole at 25 yds and lead the barrel horribly in just 10 shots. Good luck in finding a suitable bullet and load.
