The BOSS adjusts timing of barrel vibrations so the bullet consistently leaves the rifle muzzle at the most advantageous time. Once the BOSS is adjusted to this "sweet spot1' for a given ammunition, your rifle will consistently deliver extraordinarily tight groups. With precision ammunition. BOSS equipped rifles of many calibers are capable of 100 yard, one hole groups. The smallest 3-shot group obtained during the BOSS development measured an incredible .051" at 100 yards, using factory loaded hunting ammunition. No longer will tion of the BOSS ranges from 30% to 50% — depending on caliber, weight of rifle, etc.
You will experience an increase in noise and concussion (muzzle blast) when a BOSS equipped rifle is fired. Hearing protectors (shooting ear plugs or muffs) should always be worn to guard against hearing damage when shooting a BOSS equipped rifle. Wear shooting glasses to protect your eyes from flying particles. Always keep a safe distance between the muzzle of your firearm and any persons nearby, as muzzle blast, debris and ejecting shells could inflict serious injury.
