Need help I’m planning on building a rem 700 6.5 cm on a carbon chassis for hunting the back country. I want to use a proof research barrel but I don’t know what would be the best length for the round. I’m also using a usoptics tpal 1.8-10x37 which weights 30oz trying to stay light thanks.

From what I’ve read on the 6.5 cm 22” at a 1:8 twist doesn’t loose to much velocity over a 26”.

That’s really up to you. From my experience and not what the internet told me, you will lose roughly 25 FPS per inch coming down from a 26” to a 20”. That is coming from several rifles with different barrel lengths and several different ammunition loading. Longer or shorter than that I have no experience. I see the exact same drop off with my .308 rifles.

A little speed one way or another makes very little difference out to any reasonable hunting range.

Thank you for the help I’ve decided that 22in should be plenty going out to 600yrd max.

Get a 12oz optic, drop to 18" barrel.

When you can cut over a pound out of the optic, it seems silly to worry about barrel length.

actually I wasn’t worry about barrel length do to weight. The performance is what I was concern with plus there’s not one single ffp scope that weights 12oz . And that’s what I like to hunt with .

What is your target weight?
Using a suppressor?
If so, for 6.5 Creed I’d roll with a Christensen Arms Ridgeline 20” or the Barrett Fieldcraft 18”. Both are threaded 5/8x24.

22” in a 6.5CM is plenty for most American game if the range is reasonable.

This one was shoot running -just stoned with a 22” Proof.

I already have a 22in bertlein #3 6.5 cm on a carbon fiber traditional stock . The rifle was built by C&h precision I don’t recommend them they lead time just happen to be shorter at the time . It shoots ok but I wanted to try another research proof barrel . I have a 26in proof research 300wm built by GAP that is so much fun to shoot. I appreciate everyone for their input .

You may need to go titanium receiver and carbon barrel to do that with a scope that weighs almost 2 lbs.

2 manners ultimate classic with M5 bottom metal (could save here)
2 action (fuzion ti saves 5 oz over bighorn origin)
3 barrel (lighter saves up to 10oz)
2.2 scope and rings (razor hd lh saves 1 pound)


9.2 pounds (7.2 with fuzion lighter/shorter barrel, new scope, could squeek under 7 with different bottom metal)

but you're also talking about $900 more to save the 5oz with action and again with new scope

Ya, and a sling and bipod ad more than people think
Yes. The Barrett for example, 5.2 lbs starting, goes to about 6 with a nice light 2-10 optic, bipod and sling bring it up to 6.8.

He's going to need to drop a pound somewhere to compensate for the tank of a scope. Christensen can get you down around 4, but you're into a $5k+ rifle by that time.

Are you married to that 2lb scope? Reason I ask is you can spend silly money going after a couple oz on the rifle when a Leupold VX3 LRP (it’s ffp) will drop 10oz off your glass weight. You could easily spend over a grand and lose a good chunk of velocity trying to cut that much weight from an already ultralight rifle. Leupold isn’t perfect but they can be your best friend when building a hunting rig for the mountains.

It’s ok I received a 20oz a NF nxs scope today in the mail today that should get me closer to the weight Ti receiver and fluted bolt should be ok.👍🏼
