Hi All, I have a Winchester Model 70 Extreme SS in a 30-06 that is only a few years old, but I reload and shoot a LOT. I think my barrel may be coming to the end it's life in the near future. I have been very happy with accuracy to this point as I am getting .3 to .5" 100 yard groups shooting Hornady ELDX in 178 grains using H4350 running at 2793fps. I have a Swaro X5 on this gun. So, I am looking for suggestions on my options to re-barrel this gun. Are there high quality pre-fab barrels I should look at or simply go to a full gun-smith re-do? Or, the final option, do I step up to more of a semi-custom or full custom rifle? Thanks in advance for the help.
