I have a proof cf sendero on my prc and have no issues with it walking after multiple shots. On my saum I have a rem varmin steel( heavier by over a pound) and when I rebarrel it, I think I'm going to go with a rock creek or mullerworks cf from pederson precision. If you look at proofs website the difference in sendero and light is only a few oz so I'd go with sendero over light.

OP, would it be fair to say that, if for CF a much better choice is Sendero, that your question would be?

From an accuracy potential standpoint, is there going to be a difference between a sendero (not lite) contour and a #3 steel brux barrel?

I'm in the process of gathering parts for a 7mm rem mag build and wanted to see if anyone had some input on barrel contours.

I have a stock that can fit up to a sendero lite barrel, but I originally wanted to just go with a #3 steel barrel.

From an accuracy potential standpoint, is there going to be a difference between a sendero lite contour and a #3 steel brux barrel?

I have heard with magnums and the lite contour it can be a little finicky. According to specs, they're about identical in weight with a 24" finished length - both listed at 3 lbs.

Planning on shooting 143gr hammer hunters, 160 accubonds and 180gr berger hybrids.

Thanks for any help!

Which one would be lighter?

If you want super light, my post is not for you. I found a Brux #3 SS to be a really nice fit. Cut some shank off to make it lighter.

CF barrels have their place, but pretty much all comp shooters use premium SS blanks for a reason. They shoot better.

I'd rather less steel than doubling my price for something that should shoot as well.

Thanks for the replies - with my stock choice, it's steel #3,4 or Sendero lite

Trying to get to 7lbs or less with a trued 700 action and 24" barrel

Both of my Bartlein 2B and 3 barrels are great shooters. The 3 is a 300 win mag and the 2B is a 7 SAUM. I have had problems in the past like others with Carbon barrels walking after a few shoots. My Proof on my 300 Norma Mag Imp is the best carbon barrel so far. I can get 5 rounds before I have to let it cool.

All 3 rifles are great cold bore shooters as well. I like to dirty the bore right before I go hunting.

Good luck!

Where do you find the contours for the Bartlein's? I can't find it on the website.

Blank contour underneath the carbon is what I am interested in. I see they have ready made that state No4, but not sure if that is the steel under the carbon or the contour after the carbon is laid on.

I don't see where they advertise the blank contour under the carbon. The stated #4 is the finished contour after the carbon is laid on. Matches their #4 steel barrel contour. Same/same for their #13 CFW which is a sendero/varmint contour.

My 7 RM has a Bartlein #3 flutted 1:8 24 inches. It shoots lights out.
