Favorite load is using surplus pulled 647 grain ball with surplus WC860 powder at 220 grains. Start at 210 grains and work up. Surplus powders do vary in burn rate and requires working up EVERY different lot. Surplus IMR 5010 start at 215 and work up to 225 grains with 643-690 grain bullets. Don't load any match loads, just use surplus components myself.
