Pondering doing a build with the 6.5 Creedmoor. This will be a powerline, bean field and mountain goat hunting rifle. Being I do reload which barrel length(24"or26") would be best or optimal? For those of you having this rifle at the specified lengths what are your velocities with 120to140grn bullets. Thanks in advance!
 
I went from a 24" 8tw Proof CF to a 22" 7.5tw Proof CF barrel and am much happier with the shorter barrel. The velocity difference was minimal, about less than 20fps If I recall in most cases.

I’ve got a 22” sendero light being chambered now. Excited to get it back. One thing to note is the proof profiles don’t match up to traditional contours. Their sendero lite is closer to a medium Palma steel.

For what its worth when i contacted Proof about this they recommended the sendero profile if your running a can full time.
 
My 24" barrel is spitting out 140 hybrids at 2830 fps (2850 fps with suppressor). It's a Benchmark not a Proof though. I used to shoot 26" barrels in 6.5 creedmoor, but I've since gone to 24".

With a carbon fiber barrel, a 24" barrel should still be light yet provide some nice velocity.

K are you using RL26 with the 140s?

I forgot to add. My 22" Proof CF barrel is running 127gr LRX @ 2997 fps with RL16 and Hornady Brass. 140gr ELD-M @ 2749 FPS with H4350 and Hornady Brass and 147's around 2850-2870 fps (can't recall) with RL26 and Hornady Brass.

I'm sure I can squeeze more out of the 140's with RL16 and different brass but it shoots fine and I have another 6.5cm and extra barrel to play around with and not push it on the Proof.

I’m doing the same thing basically. I’m adding a 6.5 Creedmoor to my 6 Creedmoor build. I’m either using the WTO Switch Lug or index up to the recoil lug. I was going with a 22” but decided on a 20” Proof.

Im loving this thread. I am going to start a Defiance/Proof build and I was thinking of a 20" in 6.5CM. This will be a hunter, target, etc, rifle more for fun within 1000yds.The build will go into my current McMillan stock that has a medium Palma barrel.

I tend to shoot my AIAX in 6.5CM and .308 most,(Factory Hornady 140ELD's) but want to have a traditional bolt. Any feedback or direction would be helpful. Thank you in advance.

Right now I’ve got a custom Stiller Tac 30 6 Creedmoor with a 22” Krieger light Palma in a XLR Chassis. I’ll be putting it in a Manners HH5 adding the 20” Proof Carbon. Full time suppressed so short barrel is welcome.

Just sent my Defiance action off to get ion bonded and pulled the trigger on a new Proof carbon barrel this afternoon. Good things to come soon!!

This post has been awhile ago but I’m having a barreled action built real similar. What stock is that and what j
kind of weight is the rig? Thanks ahead of time.

Manners PRS2 with the barricade mini chassis. I don’t really remember the weight but I think around 12 pounds or so.

Per my new(-ish) Speer manual; shortening the 6.5 Creedmoor will lose velocity by about 20fps per inch for barrels under 24" in length.

My bolt gun barrels are 20" (223 & 7.62x39), 24"(223 & 308), and 28" (260 & 7.62x54R)).

My AR barrels are 16" (223), 20" (6.5G & 308), and 24" 2-223 & 6.5G).

Yes sir it does. The proof barrels are supposed to be faster barrels than some of the other steel barrels. It should be about a month before my 6.5 is finished. I’m excited to see results.
