I have a Browning A-Bolt 300WSM, no Boss. Shooting 1" groups at 100 yards using the 150gr Balistic Silvertips which run $25 at Gander Mountain & Bass Pro. Recoil is less than that of a 7mm. My Brother has a 7mm w/ Boss and the recoil on mine is about the same, maybe a little less. It is definetly not as much as my shotgun with slugs.
