Proof vs. Bartlein/Krieger

I am considering a Proof barrel for a hunting rig for the weight savings and because they look cool/different. For those of you who have run these barrels, how is the accuracy? Are you seeing Bartlein/Krieger levels of accuracy from Proof? Given the cost of a custom build and the ADDED cost of a Proof, I am just curious how these barrels compare to the best of the all-steel cut-rifled lot.

Also, now that Proof is adding more and more OEM customers (eg. Weatherby), has anyone noticed a drop off in quality in recent months?

Your first hand experience is much appreciated.

You can check some of my previous posts doing load data and such with a proof. I’m actually trying to source a full bull at the moment and have a 338 sendero being turned into a 338 RUM on a PRS 1 and Defiance action. I’ll buy proof from here on out if it fits the application.

I have 5 Proof carbon barrels now, all shoot just as good as my Bartlein guns. Just started load development today on my newest one in 6.5 creed, 15 rounds down the pipe and load developement was pretty easy. This is what I got right out the gate. I'll tweak it somemore when i get over 100rds through it.

for pure hunting purposes, get a pencil thin barrel from any of those three.
there is no first shot difference if its spun by a good smith.
you dont shoot groups at animals...maybe Pdogs on a field. they wind up being groups by volume

If you run suppressed then you're shit out of luck with a pencil contour. I also like beefier stocks, my main hunting rifle is on an Mcmillan HTG. A pencil barrel in an HTG just looks silly.

Wyfox, i agree 100%. skinny barrel in a huge channel looks like sh@t.
only issue is that im getting old and lazy and dont want to hump the weight. lol

Wyfox, what was the range on that group? Assuming 100 yards, that looks to be about 0.75 MOA? In the world of custom barrels and chambers, that's pretty average. Am I missing something? Please don't take this as an affront, I am just curious.

I have set up two Proof CF barrels. Both were 5.56 AR rigs. Both are sub 1/2 MOA 5 shot groups and 40FPS FASTER than any other barrels I have tried including the ones you mentioned.

Looking at the grid and assuming they are 1/2 inch squares. It looks like .5 MOA to me.

Brand new barrel first group shot after zero. Haven't even done an OCW test yet. That was a load recipe from my AI. By the way it's .61 center to center and I had a stiff crosswind. All my Proofs shoot less than .5" after load developement. I dont get to serious on load developement until I have over 100rds through the barrel.

Just bought my first PROOF carbon for my AI AT in 6.5 Creedmor. Had a Bartlein prior. Bartlein was awesome but the PROOF is better - smaller groups, less coldbore deviation, less heating and lighter. They have ruined me. Will likely always go PROOF. Barrel is also a work of art. Beautiful finish

I have a couple of Bartleins - They shoot great - 1/4 to 1/2 MOA. I have two Proofs (6x47 and .280 Ackley) and they shoot just as good ... if not better than the Bartlein. I have not seen any POI shifts as the barrel heats up and for me the extra $$ is worth the weight reduction.

FWIW, I started a thread on a "Go Lite" PRS rifle that I built. I have some pictures of groups including a 20+ round string to "stress test" the proof carbon fibre barrel:

I always ran Bartlien barrels on all my rifle's. No more. Both my main hunting rifles, 6 creedmoor and 6.5x284 Norma are Proof carbon barrels in Manners EH1 stocks.

As mentioned above, groups are unreal and I am not noticing any coldbore deviation worth mentioning,

The barrel hasn't even sped up, I'd say impressive/promising right off the bat.

I'd go with the Proof. Interestingly enough, my first 6.5 creedmoor was a Kreiger, followed by a Bartlein, and then two Proofs. I didn't have a good experience with my Bartlein so I popped it off early and replaced it with my first Proof that ended up with a bum chamber job but it still shot half moa or less with prime and handloads. I'm still working in my replacement but so far its about half moa, sometimes little less.

+1 What Mudol said.

My experience is that all of the barrels mentioned (Kreiger, Bartlein, Proof ... ) will shoot if they are chambered/fitted by a good gunsmith.

The extra $$ for the proof is for a significant weight reduction and the coolness of carbon if you are into that ...

Agree with @300ATT. The big draw is weight savings when going with a heavier contour.

IME, its a pretty big game changer that allows you to walk that line closer on the side of a hunting rifle weight but with the rigidity of a bigger contour.

A proof barrel does allow you to build a true dual purpose hunting/match rifle. I have two rifles on mausingfields that weigh in at 10-11 pounds with optics and they are as accurate and consistent as my 16-18 pound AI's

Was this the TL3 with the barloc you posted the pics of?
