Carbon Fiber Barrel Harmonics Video

Benchmark is among the best, their deep fluted barrels are stupid light, sub 3lbs at 24" in a #5 contour.
I had a good conversation with one of their builders and he basically said they only offer a CF wrapped barrel cuz they're trendy, there's zero advantage otherwise.

Yep. Same thing I was told. But hey, I needed a pretty rifle. All mine are beat to heck and put together with superglue and used parts,…. Once I get my rifle back from them, I'll see how it goes. Almost wish I'd of just done a SS light sendero,….. Living just an hour away from them is bad for my wallet,….

Proof has my top vote for CF barrels
i have built dozens of sm frame and lr frame autos and bartlien was the only barrel i was useing for top accuracy,til i wanted a lighter weight lr frame , the proof was $100-$150 more than barts barrel , but alot lighter. The groups were awesome and half the ammo to break in ,on the pre chambered barrels i buy from them , most break in comes from how sharp the reamer was during chambering , i feel proof MAYBE is lapping the throat after chambering as i bore scope every barrel before assembly , i know that my experience has been a lower amount of ammo and cleaning to zero copper with proof pre chambered ar style barrels Bartlien barrels are great barrels and break in lower than most cut rifle barrels also but its really up to the reamer the smith is using.
CF is stiffer than normal steel based barrels and i have had less flyers from cold bore shots at long range with them .
i shoot far and often and a hunter at heart so cold bore first hits are my primary goal .
223 wylde
6.5 grendel
6.5 creed
260 rem
308 win
i have only built one 6mm arc and had no real testing ammo or dies to fully test the accuracy , i do know the owner is very happy with factory ammo he is using

Funny story, I bought a carbon barrel from benchmark last November. It's actually up there right now getting chambered. I was so excited and talking out my *** about the advantages I'd learned from the internet. Kourtney was quick to educate me on carbon barrels. The glue and resin in carbon barrels holds the heat, weight savings on a benchmark carbon is minimal because they don't turn them down as much as proof and carbon is done mostly for aesthetics.
She did however explain to me how is does make a difference in harmonics a little and how well they shoot. So, that's the last time I talk out my *** to the pros about what I learned on the internet,…. Since it's my first Barbie gun I don't mind having the carbon barrel to up the aesthetic nature. I know it will shoot well either way. Benchmark is a fantastic place!

Well then that is a good enough reason for me not to buy one, I buy carbon fiber for the weight savings so if they aren't light then that's not much of a benefit.

I have a 28" Proof 6.5 Creedmoor savage Prefit barrel that replaced a 26" steel barrel of the same taper, the 28" proof is 50oz compared to 89 oz for the steel. I also had two 18" 6.5 Barrels, the steel marksman contour was 50oz and the carbon is 36 oz.

I've been shooting my 6.5 x 284 Norma for about eight years I've been through 3 proof barrels and 1 bartlein on it currently all have been shooters!

You missed the part about Benchmark fluted barrels, they're as light or lighter than any CF barrel up to #5 contour, which is WAY stiffer than a Proof bull.

I'm not disputing SS is stiffer than CF with the same contour, but I am having a difficult time understanding your statement. If CF is approximately 2 times stiffer than than SS by weight, this makes your comment a head scratcher. Oh well, here we go again. It really doesn't matter. Both barrels are sufficiently stiff and proven to perform.

I do not recall ever seeing a carbon wrap barrel on a benchrest rifle nor an F Class rifle.

Hello!

Except I run all suppressed which means I'd need a #6 at the minimum so #5 and smaller being lighter doesn't really help me.

I've got a CF barrel at the smith right now being chambered in 6.5-284 Norma. What barrel length and velocities are you finding in your?
That's a good looking rifle btw!

A #3 steel barrel is stiffer than a Proof CF bull

I shoot 100% suppressed as well, a benchmark #5 will give you a .735 shoulder at 24" which is perfect for any 5/8×24 can.
In reality though suppressors are pretty cumbersome on barrels over 20-22" so you can use a #4 at those lengths

Knowing how to tune a load is key in your reloading, many have no clue. When a gunsmith chambers a barrel, indicating the throat into .0001 run out, you are going to have super accuracy on a std sporter weight barrel, take it to the next level with a good muzzle break. Getting that barrel dialed into the degree that I mention solves a lot of ills in accuracy, and puts a stop to reloaders chasing their tails on load development. I am not a gunsmith, but I know good gunsmiths that are dedicated to the trade.

I expect 1/4"-3/8" out of my hunting rifles, and more than often, I get better accuracy than this. None of my hunting rifles are super fancy or super expensive.

All of the ****ing match comments aside, I own heavy profile steel barrels and Sendero profile carbon barrels of various manufacture. Both are equally accurate but the CF is significantly lighter in weight.
For a bench gun that matters not, but in a hunting rig it matters a lot.
