6.5 Creedmoor Barrel Length

[Ralph Littlefield]

I am ready for a new barrel on my Savage model 10. It is in an Ashbury Precision Ordnance Saber chassis. I am limited to 600 yds, have an inventory of 147 ELD's, and H4350, Varget & RL16, I assume 8 twist and 24" length is what I should be looking at, but would consider other suggestions. Is there any disadvantage to going a little longer in length? It will be shot from a bench.

In the 2022 camp Perry Palma match last week, a guy with a 22” 6.5 Creedmoor won the optics class, shooting a 150 -6? X at 1000 yards.

My 6.5 has a 30” barrel and I dropped several points at 1000.

I think a 24” will do you just fine.

I bet a 27 inch or so would balance fine on a bench gun.

48" So you can get enough velocity out of the Need Moor!

No disadvantages in going longer with a quality barrel blank. Gain a smidge of velocity but its only 600 yards. Only shooting from a bench heavier barrel wont matter your not hiking with it. Biggest disadvantage i see is the gamble of those bullets making it to the target . Good luck with the new barrel

It would appear, from your comment you have never shot or worked with one beyond 400 yards.

6.5 Creedmoor- Effects of Barrel Length on Velocity 2019

The above is a great write up from a very reputable source.

I have gone to 30-inch on pretty much all my non-hunting rifles and 32 on my F-Class rifles. If nothing esle, it lets me run things at lower pressures. In my 6.5CMs, I shoot 153.5s and 156 EOLs and the 30-inch barrels allow me to shoot these over 2800 comfortably and accurately.

Shorter is fine but longer can have some benefits.

Anywhere between 23-26 work really well with different profiles and muzzle devices. For target applications typically largest diameter at the muzzle your weight tolerance allows. The straighter the taper the better. Think Palmas instead of varmints. Thread it for a Mike Ezell tuner or ats tuner as those two do some different things that are nice in their own regard.

Think of barrel length in terms of brass life. Longer barrel = higher velocity at lower pressure.

I have competed with a NeedMoor out to 600 yds in our local Long Range precision matches. I'm now shooting a 6 dasher and a 6X47 lapua for the matches. Shooting better bullets in the 2900-3000 fps range.
I'm using 26" barrels. It's not called a "Need Moor" for nothing. BTW my 260 ACK with 142 Sierra will shoot circles around the "Need Moor"!

LOL! Right! The Creedmoor in a tight group with your rounds out around the edges!

You shooting paper or steel targets with the creed verse your 260 ? Just curious. 600 yards is point blank range to me. I have all 3 6.5 creed 260 and 260ai they all shoot roughly the same at 100 dont really see a difference untill about 1300 to 1400 yards for me. Velocity is just a dial on the scope for drop . If you cant call wind they all miss .

Seen this out there. Looks like a poll

Shooting steel, loli pops and grass rats!

 

[10XSHOOTER]

I see by the chart, more people are shooting the 6 Creedmoor than the 6.5 Need moor. With 26" barrels

 

[10XSHOOTER]

I'm now working up a .223 AI with 80 gr bullets for the same match.
It has a 24" tube on it.

 

[Bill K]

Part of the reason I shoot the 6 & 6.5 CM, they just do the job, with a little dialing on the scope, after working up a chart for the longer ranges. Easy to be right on, with a good solid and steady hold.

I think you Need moor reassurance. You obviously have doubts about the choices you've made in calibers and probably in life as well. This is not the place for you to receive that reassurance.

According to that chart 26 inch is the best barrel for every thing. Thats good to know
