rifles in 6.5 Creedmore?

[Slimbo]

Anyone have quick load data for a 6.5 creedmoor doing 3000 with 147s?

LOL. I’m over max to get 2675 in a 22” barrel. Wouldn’t be interested in chasing 3000FPS, even in a 26” barrel. May end in a kaboom.

 

[ScottMisfits]

I just picked up a Remington t 700 Varmint ADL to build up. It’s got the 26” Varmint barrel. Using some Hornady American Gunner 140 grain factory loads I was getting 2700+ FPS. I can see 3000 being plausible.

Wby uses 1-8 twist for the 6.5cm and 6.5-300 bee.

Ooo. This close.

And ew. It’s belted.

6.5 creedmoor. 42 grains of rl-17, a cci large mag primer, 147 eld m, hornady brass seated to 2.845" get me to 2820 fps, with a 24" barrel. no pressure signs, solid accuracy.

 

[kman300]

It takes all of 30 seconds to go to the Weatherby website and look at the specifications for a mkv or vanguard to see it's a 1-8 twist.

They only make the rifles though, right? What would they know when wikipedia says otherwise.

Ooo. This close.

Wears a belt.

Tokay444 SAYS :

You can hit 3200 fps with ease in a 6.5 CM case with a 120 gr bullet. 3000 is 147gr speeds in 6.5CM.
It really isn't though. Just an efficient case.

WOW ! How long a Barrel ? What Powder and Primer ? What Case ? RJ

Barrel Length: 24”
Twist: 1-8’’
Case: Hornady
Trim-to Length: 1.910’’
Primer: Winchester WLR

I was curious and just googled it..

 

[ballistic acorn]

according to QUICKLOAD, desk top drag strip. a 147 grain eldm with 45 grains of rl17 @ 2.8" coal 6.5 the phantom hornady creedmoor:
45 grain rl17
75k psi
2942 fps
100.7% case fill.
24" barrel

45.5 grains rl17
77k psi
2970 fps
102% case capacity
24" barrel

26 inch barrel
45.5 grains rl17
77k psi
102%
3013 fps

real world... i have run up to 43 grains rl17 in a slower barrel factory rem trying to get to 2800 which i nearly did with the 147 eldm in 6.5 creedmoor
with no pressure signs
but 42 gr rl 17 was what i settled on in my current rifle it was accurate so i didnt need to push it to get the velocity(2800)

 

[ballistic acorn]

oh yeah 58k to 62k psi is the redline for the young whippersnapper 6.5 creedmoor depending on what book you read. i am sure there is a sammi spec out there

 

[Tokay444]

That’s guys. I was watching the game.

 

[Buckmastr]

There has never been a hunting cartridge more exaggerated in its ability then the 6.5 creedmoor.

 

[bearkilr]

RL26 and a good long seating depth and you'll get there. Try that with a 260 remmy and OOPS you're out of magazine length.
There's no magic to it. Short and fat cases are more efficient than long skinny ones of the same volume.

See that's the part I don't get. I can understand efficient case,etc, but why push it to what many would consider "beyond its limit? Just buy a 6.5x55 or a 264 WM.

I like the 308 because it's a nice shooting round and efficient. I don't try to load it to 30-06 velocities or more. If I want that, I'll use a 30-06 or 300 WinMag.
Same goes for 223. If I need more speed, I'll just use a 22-250.

I LIKE the cartridge and have 2 rifles chambered in it ! BUT there are a LOT of FPS liars out there ! 3000 fps - 147 gr-ers ! : RJ

 

[Rembo]

I've owned 5 different Creedmoors, still have two. Settled on a heavy one and a light one, a Sako Roughtech Range and a Christensen Mesa.

So there were 3 of them out there for sale from me alone.

Nothing really special about it. Just a 6.5 round a little shorter than a 260. Fits a 2.80" mag box with long bullets a bit better than the 260.
They all work.

 

[todbartell]

Anyone have quick load data for a 6.5 creedmoor doing 3000 with 147s?

With RL26 it could be in the 69,000psi range. Hot but not CMFBI hot

 

[todbartell]

Here's 47.8grs RL26 under the 147gr ELD loaded to 2.926" OAL in my 20" 6.5cm

@ 35 fps per inch, you could expect a 26" rifle to do approx 2958 fps. This wasn't a dangerous load in my rifle. Brass was Lapua too which is shy on capacity compared to Hornady. Temperature was -4c when I radar'd that load


I've settled on 46.8grs RL26 which gives 2715 fps, here's a string from a few weeks ago @ +14c

With a G7 BC of .315 (G1 .617), from the 20" barrel the 2715 fps MV load doesn't dip below 1350 fps impact speed until 1200 yards. A 26" barrel would push that to 1330Y. To compare, the long standard 175gr SMK Gold Medal load from a 308 would carry 1350 fps to 850Y and dishes out more recoil in the process. Wind deflection is 50% more with the 308

@ 35 fps per inch, you could expect a 26" rifle to do approx 2958 fps. This wasn't a dangerous load in my rifle. Brass was Lapua too which is shy on capacity compared to Hornady. Temperature was -4c when I radar'd that load

35 fps per inch is possibly another creedmoor exaggeration based on this article. Suggest 14-20 fps per inch.

[todbartell]

just punched it up and Quickload says 27-28 fps per inch with H4350 / RL26

The 2019 update to the article you linked to shows 23 fps per inch average from 26" to 20" across the six differnt loads tested
