It is a Model 7 "magnum sporter" which in reality is a Model 700 "sporter" contour. I.e. it finishes out at .660 at the muzzle.

If I were getting a full custom barrel contour for a lightweight rig, I would go .600 at the muzzle between 20 or 22", and get a replica of the Winchester Featherweight shank.

If it was on a 338/06, I'd go with the FWT shank but increase the muzzle diameter to .650+

E, no doubt the Winchester taper is thin on the muzzle, the FWT, but vs a Rem which tapers quickly to a point then keeps the same dia. the Win. seems to have a little more beef midway in the bbl, but I don't have two in front to compare. Obviously they all work, to varying degrees. I take it very thin tubes are more prone to NOT shoot well if a not so great factory tube, and/or it is a bbl with stress and other 'issues'...true?

Looks like .600 muzzle O.D. is a good minimum in a quality bbl.

Good points, thanks.

I understand that Charlie Sisk developed his guidlines because he found that most of his customers won't spend much time developing loads. But a properly put together light, even a light, long, whippy barrel will shoot at least some loads quite well. Just not nearly as many as a much stiffer one. My 24 inch, Lt. Mtn. Pac-Nor has, and does, shoot some ammo into .5, even a few times down to .2-.3 MOA. But not nearly as many as my #1 contour barreled rifles.
The two most important things in building a light mountain rifle are (1) make sure all of the pieces make your weight goals, and (2) make sure that rifle doesn't end up muzzle light. I prefer it balance on the front reciever ring.
Any top quality barrel, properly installed, should shoot at least a few loads plenty good enough for a light big game rifle. E

I kinda like the 24" 700 CDL-SF barrel in 260, but I would opt for a lighter 22" LSS-MR barrel is I was going to carry said rifle for miles and miles.

Thanks guys, E - agree, when you build a big game rifle, more is in mind besides simply bench rested groups, but often customs will please even if on the light side based on most owners reports.
