Getting a nice star shape at end of muzzle. Bullet lube in prefect circle on case at the mouth. Groups aren't panning out like I want. Powder heavy dose of 296 powder cast 250 grain bullet BHN not sure. Off for 5 days so I have time to play. Looking for groups under 1.5'' at 50 yards and trying for groups at 100 yards of 3'' or less off pistol rest or sand bags. And no I'm not using my S&W 629.
