Many moons ago I bought a Winchester stainless model 70 7mm with a "BOSS" factory installed. I have shoulder problems (artificial now) and was very sensitive to recoil but wanted to get a little above my 25-06. Several amazing results with this factory rifle. First I found the boss would dial in factory ammo to less than one minute of angle at 100 yds. It performed to 1/2 minute of angle with reloads. Recoil was very mild. I have killed over fifty animals at long range (200-600 yds,). Black bear, elk, and white tailed deer. I am yet to wound or lose an animal. The boss is a major contributor to this in my opinion. It really works and is not a gimmick. I see very few if any on rifles in gun shops and in the field. Why don't more hunters use a boss to make their rifles far more accurate and reduce recoil? Am I the only one with this experience?
