weatherby barrel threading

[jay775]

I have a Weatherby Vanguard in 300Win Mag that I would like to thread to eventually put on a suppressor. My barrel diameter at the muzzle is .612". I was told I need 5/8-24 threading . The only way that will work is by shortening barrel to about 22". Is it possible to thread barrel to 9/16-24 and put on a thread adapter without any negative results?

I would rather not shorten barrel. But if I did how much would that effect downrange results at a max of 800 yds?

I really don't care for the idea. Too much 'cobbling'. Thread the 24" barrel for 9/16 (.562) and install a sleeve with a 5/8" O.D. (.625). Now cut the 5/8" thread and you'll see you gained nothing. Shortening a .300 WM barrel to 22" makes no sense. Too much lost to call the result "good".
