Mine likes Sierra 100g BTHP Match and 100BT spitzers best of all, with Reloder22 powder. Group testing - 3 shot groups - in the .2's to .3's. Working load is 72.0gr= 4002 fps., 7000' altitude. Other lighter bullets factory and custom didn't shoot as well. This is a rockchuck gun, not a hunting gun. Braked heavy 28" Hart barrel, 12twist, minimal neck and 0 freebore.
