I have a Weatherby Mark V Accumark chambered in 300 WBY. It shoots sub-MOA groups averaging around .88 in size. The accuracy is pretty good but I would like to get down to 1/2 MOA groups if possible. The rifle has the stock Criterion #3 taper barrel. I am considering purchasing a new barrel and having a gunsmith mount it on the gun but am not sure how to go about this process. I also want to have a RRS Arca plate mounted to the stock. I would appreciate any advice as to what would be a great barrel for this gun and if there are recommended gunsmiths that can do a good job changing the barrel. Thanks!
