6.5 creedmoor suppressed optimal barrel length

[Kosinskijim]

Looking to rebarrel my 6.5 creedmoor, this will be a hunting rifle, I have a dead air nomad ti waiting on approval, barreled action currently sits in a krg bravo, Looking for opinions on barrel length, im currently thinking about a 20" but toying with the idea of 18", I would likely keep my shots with this rifle 300 ish.

Thanks!

I built myself a 48cm, or 19" semiweight barrel for Tikka T3x and run an Ase Utra Radien suppressor on it. 8" twist, stainless Lothar Walther profiled blank. Stock barrel was 24", and with a suppressor on it was simply too long for my taste.
I think I got it just right, as it handles extremely well and shoots very accurately out to 600meters even with somewhat mild handloads.

Any idea on velocity? I'm thinking either 127 lrx or 120 ballistic tips.

At 300 yards you can go to 16" no problem, 130 eld or tmk will be very destructive. I'm at 18" and should have enough velocity for the bullets to perform at 600+ yards.

Monos suck at tissue destruction.

What bullet do you recommend? Was thinking 120 nosler BT

130 eld, 130 tmk, 143 eldx, 140 eld, 147 eld. Basically the stars of this thread.

6.5 Creedmoor/260 for Deer, Elk, and whatever else.....

I wanted a super lightweight mule deer gun. So 4 years ago i got a tikka superlite in 6.5cm. I load 4350 and a 143gr eldx. I don't have any pictures of the carnage and these are the only 4 animals this gun has shot at. All dropped on impact 330 yards hit behind the shoulder and exited out the...

I did 20” but if I was keeping shots inside 300 I would just use my 223. If I had to use the 6.5 though I would cut to 16” and use a 130-140eld or 130 TMK

When I cut my 6.5 it will be 20”

I cut my Tikka to 20". I'm getting 2924 w/130 ELDm using a Nomad can. I almost always carry my rifle in a Gun Bearer and do not typically have an issue with the length.

120 gr NBT like 39-40 gr of Varget, but factory rounds work just fine to 400 yards on deer from my 22 inch barrel. You should be fine with 18 inches and suppressor to 300.

I've had 16", 18", 20", 22", and 24" 6.5 Creedmoors that I ran suppressed. 16" and 18" had a lot of loose carbon shit in the can from unburnt powder. One longer range session (150 rounds or so) with the 18" without removal of the can afterwards and storing it muzzle up cause me some issues and I had to clean the shit out of it, couldnt chamber rounds and had a lot of carbon back in the lugs too causing the action to not run well.

Zero issues with 20"+. Velocity wise I found 20" to be the best compromise for portability and not being neutered. The Bartlein CF barrel I'm going to have spun up for my new Impact 737 switch barrel hunting/NRL hunter rifle will be a 20" 6.5.

Rl26? Thats blazing fast. I pressured out at 2750 with my factory barrel cut to 20".

 

[J&A Outdoors]

We've built many 20-22'' creedmoors runing suppressed.

Most settle in between 2625-2750 FPS with 140 class projectiles.

That velocity is not even possible with a 20" barrel, let alone a slow Tikka barrel. He either has a happy chronograph or no chronograph and is just throwing out a number.

 

[Stache Attack]

18-21 seems to work for me, great accuracy with short thicker barrels. 6.5 creed isn’t fast I think I’m 2725 at 20” w/out a can. Consistently slow works for me

 

[brockel]

My previous 20” creedmoor tikka went 2750 with 140s. Have another at the smith getting cut to 20”. Will see what that one does when I get it back

Any idea on velocity? I'm thinking either 127 lrx or 120 ballistic tips.

My mildish load runs at 2630fps range with 143gr ELD-X, and slightly faster with 139gr Scenars. I could push it for more, but this load is stupid reliable no matter the conditions, so I'm sticking with it

I haven't tried the 120-130gr bullets that much, as the barrel clearly preferred the heavier bullets when I starter load dev. on it. I couldn't get anywhere close to the accuracy of 139gr Scenars when I tried to work up the 123gr Scenars, so I basically gave up on lighter bullets with this barrel. It sure loves the 143 eld-x when I figured out the seating depth for it.

Considering your suppressor is 7 inches long. Why not get an SBR stamp and cut your barrel at 13 inches? Giving you an overall barrel/suppressor length of 20 inches. Which would be cool ‘cause you’d have a short barrel, a suppressor and a 6.5 Creedmoor. Of course, this should only be done with a Tikka, topped with an SWFA scope.

I have thought about going the sbr route before. A 12" 6.5/308 would cover 90 percent of my hunting. Having to file paperwork to take it out of state is the only holdup.
