Not completely. The muzzle diameter is a nominal .550" that goes straight back for IIRC 16" (or maybe 14") then it tapers up the next 6 inches to the shank which should be 1.2" at the shoulder. This is for a 22" barrel. I'm typing this from memory so don't bet large sums of money on it's exact accuracy, but believe this is pretty close.
Hope that helps a little.

call pac-nor they have it in there computer. I cant remember the muzzle spec but it should be right around .550. Im pretty sure it only tapers straight for the last 6 inches but I could be wrong about that.

Thanks guys. Pleas keep it coming if you have it. I think the Douglas one is a bit off as they list a 20" OAL.

I keep meaning to measure my M700 mountain rifle barrel when I get home each night. One of these nights I'll actually remember to do this and will post the dimensions. Mine is a 22" Mountain Guide model but to the best of my knowledge that has their standard mountain rifle contour on it.

"I keep meaning to measure"
Same here. I've a take off at the house which will make it easy to measure. I'll post up specs if I get to it before Jim.

Thanks guys. Please keep it coming if you have it. I think the Douglas one is a bit off as they list a 20" OAL. Remington Contours Rem Mtn. Bbl (Douglas numbers) A = 20 B = .690 C = .550 D = 1.2 E = 13 A couple of years ago I called Douglas about making a 24" mountain rifle barrel for me (in 280REM of course) and I asked how they would do it. What I was told is that the barrel would use the dimensions above but "E" would be 17" instead of 13. Therefore the taper from .690 down to .550 would take place over 17" vice 13. It results in a slightly heavier contour due to the slower taper. I hope this helps. RH

As a FWIW, I had a Pac-Nor Remington Sporter contour barrel installed on a Model 70 (yes, a Winchester - I like the Rem sporter contour).
Anyway, for S&G and to see what would happen, I asked them to turn it down "about halfway between a standard sporter and a mountain rifle". Sporter muzzle is .650", mountain rifle muzzle is .550". The man at P-N said the way they'd do that is to start at the muzzle and make it .600", then work their way back to the first taper at B above taking off about .05" and then blend that into the 1.2" shank - which on remingtons is almost non-existent.
He said with their CNC programming he could just load up the mountain rifle program and then change the one parameter, at least I understand that's all he needed to do. He said it was pretty easy to do this.
Whole thing cost $35 plus shipping. Barrel was stainless so didn't need rebluing and they bead blasted it as part of the price.
Anyway, it turned out real nice. Not a flyweight and it didn't take too much weight off, maybe a couple-three ounces at best, but did move the balance back some. With the small amount removed it went back into the bedded stock and it's just free floated a tad more than it was, no real unsightly gap in the channel.
