Anyone who can tell me what kind of barrel I need for my sub .458 Socom-project?
I'm going for my short Rem 700, and I'm going to use mostly 405grs Rem, and 500grs Hornady -bullets.
I specially want to know if I can use a 1:14" twist, or do I HAVE to have a 1:8" twist?
Opinions please?

No. The Norwegian .458 Socom vouge was created by a man who wanted to stabilize very heavy mono bullets at sub sonic velocities.
I am making one now in 1-14 on a Ruger 14, and I have no doubts.
Our friend Pluto had no problems sub'ing his .45 Blaser, and that was not 1-8.
1-14 is recomanded by many Socom-makers in the US.

OK.
It sure make the avaliability for a barrel easier. I'll just pick a Douglas-barrel for it.
You dont have a barrel lying around, Bent?

Sorry, Buster!
But I can get Walther pretty fast if you like.
Call me at 90866577 if you are interested, I have a new reamer that needs to be used!

Visit www.300whisper.com to visit the quarterbore forums. Plenty of experience their with all forms of subsonic rounds. Their is quite a large thread specific on the 45acp.
