I have a .300 WM that kicks like h3ll too. I wanted to sell/trade it off until one day at the local gun shop the guy said exactly what another poster said here, "it only takes one round to kill the critter you are after". So with that I now you a shooting sled and small ratchet straps to secure the rifle in the sled when sighting it in. Once I think I have it sighted in I shoot three rounds and if it is acceptable, that is it, I put it away until I head out hunting. It is a very, very accurate rifle (Rem 700 Classic) and I am so glad now that I didnt get rid of it.
