Rifle Barrels

I acquired a JC barrel through some trading a while back. 6mm, 1-8" twist.
I had it fitted to a 700 Classic action I had here. Guntech did the work.
It is a very good shooter. Gathered some copper right at first, but settled
right down after round # 30 or so. It is not a contour 1...more like a 3,
but I believe he makes quality barrels.
Another one to take a look at is Benchmark. Very good quality barrels, and
a Gunnut on here is the exclusive supplier of these. I have 3 now, and they
are above reproach, IMHO. As Doug mentioned, in a contour 1, you will be
more interested in first shot accuracy than in itty bitty groups. EE.

Well - Stainless has a substantially larger coefficient of thermal expansion than Cr-Mo. If its going to cause an issue, it would be in a pencil barrel...

You could not be more wrong. Both have very similar coefficients of thermal expansion, and in fact Chromoly (41xx) series steels have a HIGHER (12.3um/m/C) coefficient of thermal expansion than the 416R (9.9um/m/C) most commonly found in rifle barrels. Even so, the actual expansion per 100 C is somewhere close to 0.0762mm per meter of material. In other words, your 1m long barrel will elongate by less than 1/10th of a millimeter if it heats to 100C. The bore will expand a paltry 0.0005mm in diameter.

So no, that has no bearing on material choice.

Stainless barrels are easier to machine and give better accuracy. This is undeniably proven. Stainless is also much easier to maintain compared to other steels, and remains in excellent condition for a very long time.
 
I would definitely stay Stainless, after the rain and fog I seen Stone sheep hunting this last year on a fly-in !

After several hours of research and speaking to a cpl bench rest guys and barrel makers the only difference or benefit to a 4, 5R or 6 groove rifling is the 5R has a taper to grooves and they say are easier to clean, one guy thought a little less resistance with the 5R rifling and should give a small edge in velocity over say a 6 groove with a 90 degree cut on the rifling ?

But no concrete evidence........either way, one of the most popular up and coming benchrest barrel makers in the US and only second in popularity to Bartein is HawkHill and they use only 4 groove !
 
one of those new carbon wrapped flavors in a number 2 contour, the light weight of a number 1 barrel with a whole lot less weight

I would suggest a CF wrapped barrel. Combo of light weight, stability, cold bore accuracy. It will cost more, but given the build, peanuts to meet the goal of light AND accurate.

I have been very happy with the CarbonSix barrels I can offer.... and quite a bit less then other offerings.

Although I can supply super thin contoured steel barrels, with the option of the CarbonSix barrel, that is where I am nudging customers. Super thin can lead to a fussy pipe

Thxs I will give you a Call ! RJ
 
Most stainless is not as slick as carbon or aloy steel. Some stainless barrels are more prone to fowling because of it. Stainless does not always mean less maint. I had a rifle with one once, and likely will not own another stainless barrel.
 
I’ve used barrels from King, Smith, Douglas, McGowan, PAC-Nor, Krieger, Shilen, Shaw, Benchmark and probably more. In all types of configuration. I’m not sure there is a clear winner, the best shooters might surprise you, and light barrels can provide exceptional accuracy with more than one shot. I think light barrels shoot better than light barrel shooters.
