New offering- 22 ARC SUBSONIC ammunition. 22 ARC loaded as a SUBSONIC round with a 70 grain SP bullet. New Hornady brass, 70 grain SP loaded to 1030 fps in 16″ barrel. This ammo was tested out of the 16″ Ruger American 22 ARC bolt rifle.
Priced per 50 rounds.
This ammo is loaded to SUBSONIC speeds for barrels from 10″ to about 18″ barrels. This subsonic ammo is not designed for barrels longer than 20″. This ammo will shoot fine out of an AR-15 rifle, but it will NOT cycle an AR-15. You can manually cycle the bolt. This ammo is designed for 1:9″ twist or faster (1:9″, 1:8″. 1:7″. etc). The 70 grain SP bullet is marginally stable in a 1:10″ twist barrel at subsonic speeds, and should not be shot in any slower twist rate.
This ammo will NOT cycle an AR-15!!! It will shoot fine out of an AR-15, but you will need to manually cycle the bolt. If you are zero’d at 100 yards with normal full power supersonic 22 ARC ammo, your point of impact (POI) with the subs will be about 6″-12″ low at 100 yards.Â
Priced per 50 rounds.
Why use a 70 grain SP (soft point) flat base, instead of a BTHP, VLD, polymer tip 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 of the same weight. The 70 grain SP flat base is a much shorter bullet than a similar weight 68/69 grain BTHP designs. This allows the 70 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 match bullet at subsonic does not benefit the shooter at all. This is why the 70 grain SP flat base bullets work well as subsonic round!
