Used Win 300 H&H new cases bumped down in Redding FL die for snug fit to chamber, loaded with 67gr RL 22, CCI 250 primer, 145gr Speer BT or FB (didn't seem to matter). Perfectly formed brass and 1/2" groups! Only caveat is that about 1 or 2 in ten cases would split at shoulder, solved by annealing at that point on brass. Brass seemed to last at least 7-10 firings with tight primer pockets-tough brass! Favorite coyote load; 120 Nosler Bal Tip & 80 gr IMR 7828--shot one hole for 3 at 100 yds. Favorite deer/elk load; 160 Nosler Partition & 80gr H1000 (3/4" at 100).
