I would highly recomend these. I put on on my .338 this past fall and what a difference. I have a Tikka and none were listed to fit. I ordered the large grind to fit and put it on. I simply put duct tape on the wood and used a 4.5" grinder to take it down. I used an old belt and disc sander combo when at my folks b/4 the hunt to finish it. Not as smooth as the prefit ones, but this gun is a worker, not a looker. Easily took better than 50% of the recoil out of the big gun.
