After the latest cleaning and borescoping of my 30+ year old Weatherby, I believe that I am in the market for a new barrel. I can't decide whether to have a Weatherby barrel put on it or an aftermarket brand. Will the aftermarket brands have the same free bore as the stock barrel? Is that an option that you can get with them? Or can the free bore be eliminated? I know that it is there in the factory barrels for the extra pressure that Weatherby cartridges generate. Any opinions would be appreciated. Thanks, GW.
