I wouldn't buy the rifle with the BOSS, but I would with the plain barrel. I handload and the BOSS won't do anything I can't accomplish by careful handloading. Noise when hunting without ear protection is the primary concern, but tuning the rifle for each different bullet weight/manufacturer is a pain.
I've recently shot Browning bolt rifles without the BOSS and they shot very well indeed, even with factory ammo!
