glad you sold it. I was tempted but for the porting. assuming they go back 2 1/2 inches from the muzzle. That would equate to a 15 inch overall barrel length, as opposed to the muzzle being threaded and a brake screwed on. Then the entire 17 1/2 would count toward velocity. Don't get me wrong. I'd love to try a ported barrel, but in order to realize a 20 inch of barrel, it would have to be 22 1/2 overall. It's a matter of personal preference. The 1:16 twist should be no big deal, even with lighter, faster bullets as long as they are thick jacketed.
Congrats to the member who bought it. I like the heavy duty concept of Tridents approach. I'd like to see an upper based upon a cut down 300 WSM case that was necked down to 450. Olympic uses such a bolt and barrel extension system for their WSSM/OSSM calibers. It would be cool to pick one of them up and have the barrel chambered and bored out to .452. I believe Dtech already offers something close in a .458. Mike does some interesting designs based upon the Olympic large face bolt and barrel extension. My 300 OSSM was a monster at the range, kicking 150gr 30 caliber bullets up to 300 WM velocities in an AR 15 frame. With only an HBAR profiled barrel it was a handful. The Gunnut inspired recoil reducer, CCWS weighted bolt and Limbsaver made it much more manageable. Not at all like a 300 WM bolt action, or even my 300 WM BAR.
