The .22 Hornet has the reputation of being tempermental to reload.I had a beautiful sako 72 that would shoot 1/2 MOA one day and all over the paper the next time out.It was .223 dia. bore and I matched the bullets.W 296,H-110 ,IMR 4227.H-4227 or LIL Gun work in this cartridge.Some won't shoot unless you use pistol primers and others need SR Mag primers.Too big a P in the A.I shot one coyote at 125 yards with a 40gr load and he bit himself and flipped over dead.Liked the cartridge hated the inconsistancies and sold the gun.It was properly glass bedded and free floated as well..............Harold
