Looking to rebarrel my Mark V Weatherby, 300 WBY, I want to stay with a heavy sporter barrel since this is a hunting rifle and I want to keep the weight down. Considering Bartlein ,Pac- Nor, Shilen, Broughton . Any favorites you guys can suggest from previous experience? Thanks for the help. If it matters I'm looking to stay with the 300 WBY chambering. Flat shooting and brass is easy to find.
