Can anybody tell me what the barrel diameters of the B and V models are?
Thanks

A No.1B factory barrel is 1.200" nominally at the barrel's shoulder and 0.625" nominally at the muzzle(26"). Basically a Shilen #4 taper cut in the right spot. The B is a complex type taper, ie sporter type.
A No.1V factory barrel is 1.150" nominally at the barrel's shoulder and 0.750" nominally at the muzzle(24" models). Pretty much of a straight taper.
Most aftermarket barrel blank makers offer these tapers.
16 turns per inch on the shank, with a nominal shank of 1.000" in diameter. Most shank threads end up in the 0.995" arena(thread major).

The taper on the "V" comes out at .705 or so on the 26" barreled models. (204 Ruger, 220 Swift and 6.5 Creedmore)
I have a custom "V" that Shilen put together for me. They carried the "V" taper on out to 28" and it's .675 at the muzzle.

The Number 1B I know and love is 26", chambered for 6MM Rem and shoots like a varmint rifle. I have the #1V in 204 Ruger and it wears a Stainless barrel and 26" length...the other V model I have is .223 Rem and it wears a 24" barrel...all shoot exceptionally well. None are as consistent shooters as say a Cooper, but at half the cost, suits me fine. The other 2 gentlemen are the experts, this just my stuff I measured.

As you know, life is full of compromises. Tis true in rifle barrel taper selection too.
As far as I know all No.1V's were a straight taper with a length of 24". An exception is the No.1V 220 swift, which has a 26" barrel, mainly due to the belief that the only real barrel for the swift is a 26"+. Then came the stainless No.1V's of which I think were 26" straight taper. Ross knows all of that stuff, I have never owned a stainless No.1...............yet.
All No.1B's I believe were 26" sporter type barrels. I really do not get into collecting anymore, so some early, early guns might be different, but are few in number if they exist; relatively speaking.
The No.1B features the sporter type barrel. Sporter barrels vary in size, weight. Most have a small straight tapered section at the breech, flowing into a complex curve down to a section of constant taper to the muzzle. Some of the taper features are done for balance, weight, style. A #1 Shilen taper is a pretty light barrel, whereas the 5.5 taper is pretty stout; but both are sporter barrels.
The No.1V is sometimes referred to as a varmint or target type taper. Starting at the breech, a short section of straight taper, follows immediately into a constant taper to the muzzle. Usually these types of barrels causes the rifle to be somewhat muzzle heavy. With that said, the extra weight helps with heat and riding of the shoot bags in varmint or target shooting.
There are subtle things about barrels, for instance, the heavier barrel is usually easier to figure out shooting wise. Sometimes the super light barrels walk with heat more easily, and are more fussy to bed and get to shoot consistently. There are techniques in barrel making, as in destressing techniques via heat, to help these things.
In my opinion the No.1B is a medium sporter taper. A compromise to the environment of the intended use. The No.1V is a bit perhaps more at home in a rest, target shooting, handles heat more better usually. You might go out to a barrel blank site, such as Danny Lilja's, to see tapers and weight calculators.
I think I will quit on this, taper is only one of the many factors that makes a good shooting barrel...........subjectively and on the technical side.
One might think of the B as a typical hunting type rifle, whereas the V is more a varmint target style(heavier). You might peruse the Ruger factory site for typical models built today. The B is temporarily(?) missing currently. I reckon there are a lot of folks that use what they got, ie a V for hunting or a B for varmints.........so there is flexibility to these guns, if you have the same flexibility.

I think SOME but not all of the difference can also be attributed to marketing. As mentioned I suspect the 220 Swift got a 26" barrel as a "V" because "That's what a takes a to make a Swift work". Which as an over bore cartridge really was true with the powders available when the Swift was introduced. With many more modern powders it's possible that it doesn't NEED a 26" barrel. BUT it's a Swift and Swifts get 26" barrels.:-)
The rifles certainly handle differently. Do they shoot much different? Not usually BUT the "V" has been made in some true Target/Varmint cartridges that the "B" hasn't, the 22 and 6mm PPCs for starters.
The heavier barrel in the "V" is theoretically stiffer and should heat up slower. As for accuracy, I"m not so sure. The two I look for accuracy out of are a "B" in 22BR and a "V" in 22PPC> The barrel on the PPC is a factory "V" barrel. It'll shoot into the .4s and every once in a while into the .3s. I believe it has a RUGER barrel.
On the other hand the 22Br started life as a "B" and the barrel came of a factory "S" in 218 Bee. This is a WILSON barrel. It's been rechambered to 22BR. The "S" and "B" barrel are the same barrel the difference is simply sights. I cut the front sight off the "S" barrel and swithed off the factory rib for Redfield bases and rings. It shoot's into the .4s and once in a while into the .3s.
The FIRST VARMINT rifle I owned and used that was mine was a non prefix 243 "B" with a Douglas barrel. It shot sub MOA and still does and has accounted for thousands of rock chucks and ground squirrels.
The point being that in terms of USEABLE accuracy, I don't think there is a lot if difference.
I don't think ALL of the stainless/laminate "V"s ended up with 26" barrels. I think it's just the 204. (The only way the 204 came as a factory "V", so I have one). ;-)
