I’ve been trying to work up a decent shooting load in my Win. M70 .30-06 using 150 and 165gr bullets on and on for the last 10 or so years using IMR-4064. Haven’t gotten anything to group less than 1” at 100 yards and it drives me crazy. Picked up some H4350 the other day. Has anyone used it with a 150-165gr bullet in .30-06 with success? I’ve tried different seating depths and at least five different primers with no drastic changes. Settled on a 180gr SST for short-ish range hunting for now using IMR-4064. The 150s I’ve been trying to get to shoot are Sierra Pro-Hunters, the 165gr bullets are Sierra GameKings.
