I tried some cast bullets in my 94 Big Bore today. I was disappointed with results. Accuracy was poor, about 4-5 inches at 50 yards. There was considerable leading in the bore as well. I was of the understanding that a bullet 1-2 thousandths over bore diameter was wanted. My bore slugs .376, best I can tell. I was using a 250 gr. bevel base bullet sized at .377 with a BHN of 16. Powder was 30 grains of IMR-3031. Do I need a slightly larger bullet? Would a lighter powder charge help? The load was right out of the RCBS Cast bullet manual. Any other ideas? Thanks, Ted
