30 Caliber 220gr RN Ballistic Tip® Hunting Bullet (50ct)

Couldn't get these bullets to stabilize in either 300 BO rifle. One is a 16 inch Ruger with 1x7 twist, other a custom built 8.5 inch AR pistol with 1x7 twist. Consistent keyholes at 50 yards and that's with numerous powder charges and 2 different powders. Changing COAL and powder charge didn't seem to help. These should be great subsonic bullets if I can get them to shoot right.

Center chest hit. Bullet entered thoracic cavity unmolested by bone. Took out leading lobe of lung and entered top of heart. Then exited mid heart. Whitetail ran 25 yards and expired.

Autopsy showed good expansion and penetration.
