The reason is that the conventional round-wire springs that come standard in these rifles exert excessive load at position two (bolt to the rear). In the case where the rifle doesn't cycle properly, we have found that the installation of our Flatwire Buffer Spring easily solves the problem.
Function has been flawless in nearly all gas-impingement operating systems without any system modifications. We have tested this ammo in various semi-automatic firearms based on the AR-10/SR-25 platforms. That means 2-Hole projectiles will have maximum energy available, while remaining subsonic at the muzzle. We have tested 2-Hole in longer-barreled bolt-action rifles and have loaded this ammo to what we consider maximum, reliable subsonic velocity. Subsonic velocities are assured in a wide range of environments due to the temperature-insensitivity of the propellant and the precise propellant charge weight. NOTE: This ammunition is designed for suppressed 308 semi-automatic usage. When looking at groups on the target it is easy to distinguish each bullet's impact. The trailing, second bullet is constructed as a wadcutter/full-diameter/open-tip. The front bullet is designed to shoot smaller groups and is assigned the designation of the ammunition's "zero". Projectile lengths are optimized to be compatible with 1-12 and faster twist rate barrels. This means that you can shoot subsonic and supersonic loads out of the same magazine with no other special considerations. 308 Winchester based semi-auto platforms with no modifications.
These bullets impact in very close proximity to each other, delivering dramatic results.ĭesigned to function and fully stabilize in a. Our 2-HOLE SUBSONIC ammo features TWO specially configured projectiles having a combined total weight of over 350 grains. ABSOLUTE 2-HOLE is a radical advancement in extreme impact subsonic ammunition.
