Experience with the 10BA(.308) only. The brakes work as intended on them, it cuts down the recoil to about a .223... Pistol grip works well, the adjusters for the stock...they're comfortable except dialing them it can be a pain. After you put the scope/bipod on there... very heavy rifle, and if/when you switch the barrel... it will get even heavier if you get a heavier contour, which I'd call the one on it stock is almost like a medium... I can't remember exactly but I want to say it's in the low .700"s
