NEW!! 30-06 SUBSONIC ammunition! New Sig or Starline 30-06 brass and 220 grain Hornady RN bullet loaded to 1030 fps in 22″ barrel. This bullet will stabilize out of a 1:12″ twist or faster****. However, it works best if you have a faster barrel twist, like a 1:11.25, 1:11″ or 1:10 twist barrel. It will shoot best with the 1:11.25″ twist or faster twist barrels. 50 rounds per order


Priced per 50 rounds.


Why use a 220 grain RN (Round Nose) flat base or 190 grain Sub-X bullet instead of a BTHP or match bullet? When shooting at subsonic speeds, bullet stability becomes a huge factor for the bullet to properly stabilize and for it to shoot well. Bullet length is a major factor in how stable it is out of the muzzle. In a given twist rate (like a 1:10″ barrel twist) and slow subsonic speeds, a shorter, flat base bullet is more stable than a longer, skinny BTHP match bullet is. The 220 grain RN flat base or 190 SUB-X bullet is a much shorter bullet than a similar weight BTHP bullet, like a 175 grain Sierra MatchKing. This allows the 220 or 190 grain to be more stable and have the potential to be more accurate at subsonic speeds than a BTHP design. BC (ballistic coefficient) is for supersonic flight, and does not matter at subsonic speeds. Having a high BC bullet at subsonic does not benefit the shooter at all. This is why these 220 RN flat base and 190 SUB-X bullets work well as subsonic round!
