GRT and Quickload will not be very accurate with these low charges, at least at first. Stay away from that velocity when working up this load, and choose something that will give under 40ksi peak pressure at just over supersonic. Note what the velocity is at max pressure. Basically aim for under 20ksi for starting load. Use either Quickload or Gordon’s Reloading Tool to find a starting load. Reason is cast bullets have much lower coefficient of friction, so the likelihood of squibs is reduced and any squibs that do occur are easily tapped out with a cleaning rod. Stay away from H110 or Win 296.įor subsonic, you’ll want cast bullets. You can even go as fast as bullseye, but I wouldn’t recommend it. IMR-4227 is a popular choice, the old time classic is 2400. You’ll want something in the slow-magnum-pistol powder burn rate or faster. With one or two notable exceptions, fast-for-caliber powders are used for heavily reduced loads (the exceptions are IMR-4895, H4895, and Shooters World Tactical).įor 308, you absolutely do not want to use varget for subsonic.
