I'm wondering for those that have a 338 AX with APS Painkiller muzzle brake if you thinks it's worth installing a recoil pad, gun weight will probably be approx 15 lbs. I know recoil tolerance for one may be different to another so I'll try to give you a feel for my recoil tolerance. I currently shoot a 300 RUM unbreaked, no recoil pad, gun weight approx 9.5 lbs and recoil is ok until I get around 10-15 rounds then it get to be less fun. Any comments or thoughts are appreciated.
