7mm-08 with Speer 160 grain SP bullet. 1040 FPS, priced per 50 rounds. Starline or Hornady brass and Speer 160 grain lead soft point bullet. This bullet will stabilize in 1:10″ twist or faster (1:9.5″, 1:9″ or faster will work fine). The 7mm-08 subsonic will NOT cycle a semi auto, since these are a lower pressure round. Priced per 50 rounds.

Why use a 160 grain Speer SP (soft point) flat base, instead of a BTHP, VLD 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″ or 1:9″ barrel twist) and slow subsonic speeds, a shorter, flat base bullet is more stable than a longer BTHP or VLD match bullet. The 160 grain Speer SP flat base is a much shorter bullet than a similar weight BTHP bullet, like a 162 A-max or 168 Berger VLD. This allows the 160 grain SP flat base 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 the 160 SP flat base bullets work well as subsonic round!
