NEW!!! 25-06 SUBSONIC ammunition. 100 grain SP @ 1040 fps in 24″ suppressed barrel (about 1020 fps in 22″ barrel). New Hornady 25-06 brass, Sierra 100 grain SP Pro Hunter bullet, Federal 210M (match) primer, all loaded at subsonic velocity! A 1:10″ twist barrel is REQUIRED for this bullet to stabilize. If you do not have a 1:10″ twist, please contact us about this ammo for bullet stability.
Note- If you are sighted in with standard full power 25-06 ammo, this subsonic round will impact about 10″-12″ low from a 100 yard zero.
Why use a 100 grain SP (soft point) flat base 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 1:8″ or 1:10″ barrel twist) and slow subsonic speeds, a shorter, flat base bullet is more stable than a longer BTHP match bullet is. The 100 grain SP flat base is a much shorter bullet than a similar weight BTHP bullet, like a Berger or similar BTHP bullet. This allows the 100 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 speeds does not benefit the shooter at all. This is why the 100 SP flat base bullets work well as a subsonic round!
