I have a stock Winchester model 70 Black Shadow in 300WSM and would like to make it into a viable long range rig. What are the most important things to do to make this a true long range hunting rifle? I know it needs a new stock and needs to be bedded and I'm sure a trigger job or after market trigger is a must but should I consider re-barreling? And what about scopes? I have a couple of Leupold long range side focus scopes I could use. One is a VXIII 6.5-20x40, 30mm tube with the long range reticle and the other is the same scope in a 4.5-14x40. Would these work? It looks like this round is capable of 1000 yard performance on deer sized game and maybe a couple hundred yards less for elk. Any thoughts or suggestions would be appreciated.
