6.5 Creedmoor Build Input

[deadduck357]

Mods if this is the wrong section, please excuse me, there are probably many sections here I could post my questions.

I'm looking at my first custom built rifle and have some questions that I thought many here could help with.

Let me start with what I know I want

1) Caliber - 6.5 Creedmoor

2) Barrel Length - Not less than 22" and not greater than 24"

3) Barrel Fluting - 6 groove

4) Rifling - 5R (or 5C)

5) Barrel Material - Stainless Steel

The set-up I'm looking for is a do-it-all rig. For long range hunting, long range target, a 900m rifle.

I haven't decided on which action yet.

What y'all could help me with is:

1) What barrel length would be best with the 6.5cm, 22" or 24" ?

2) What rifling twist rate is ideal for the 6.5cm, 1/8 or 1/8.5 ?

3) What contour is ideal for a fluted 22-24" SS barrel for both field & range ?

4) What finish/process is best for blackening stainless steel ?

I know there will be more questions later, but for now I want to get a barrel on order.

Thanks for any input

Re: 6.5 Creedmoor Build Input

With the 6.5 CM, you want your barrel as long as possible, so if your max is 24, get that. As far as twist rate, depends on what tips you want to use. The heavier bullets would like the 1:8 twist better.

Re: 6.5 Creedmoor Build Input

1.Dennis at creedmoor sports recommends longer barrels If 24 is as long as you want to go then I would go 24" if you want to go 22" I would go 6.5x47 lapua
2. 1-8 twist will be best
3. I would go #6 or #7
4. I like cerokote best
5. I would go McMillan HTG stock

Re: 6.5 Creedmoor Build Input

I should have mentioned, 129gr projectiles would be the main weight grain, but want the twist rate to cover 120gr through 140gr.

Re: 6.5 Creedmoor Build Input

24" fluted #7 contour with an 8 twist will handle what you want it to do. The barrel will be heavy enough but not too heavy with the fluting and length. Cerakote it black and it will be fine. Check out the Manners T3 or T stock for the stock.

You going to be handloading or shooting the 129grn SST Superformance ammo?

Re: 6.5 Creedmoor Build Input

Go long 28 inches on the barrel!!

You want to get the most velocity possible!

Re: 6.5 Creedmoor Build Input

I suggest a Tubb contour or medium palma.Personally I'd be looking at a 26-28" barrel to keep the velocities up.

A friend of mine put a 21.5" barrel on his 6.5x47L and he's only getting 2670fps with 140JLK's.At 2750fps he was getting a sticky bolt.

That's a good suggestion. I would have said longer but he seemed like he was set on 24" for some reason.

Dave Emary(Hornady) recommended the 22".

I was having a hard time deciding between the 6.5 CM and the 6.5 L, both look great for what I want. But everything keeps pointing to the Creedmoor. Creedmoor has lower pressures than the Lapua, so theoretical longer barrel life, right ? Also just for a deciding factor I searched pricing for cases and factory loaded ammo and the Creedmoor was considerably cheaper. Found some loaded CM for $18 - $22, the cheapest I could find 6.5L was like $49

Yes, I was looking at the 129gr as my main, BUT want the twist to cover 120-140. This is why I was wondering about 8.5 twist ???

Will be reloading but want factory available also.

I understand, but I hate taking my M700 VLS 260 in the field, it sucks for stalking.

Re: 6.5 Creedmoor Build Input

I was looking at a Krieger 5R barrel, maybe a Broughton 5C. What other barrel manufacturers use 5R or similar(5C) ?

Re: 6.5 Creedmoor Build Input

Kreiger 8 twist will cover all your needs in a medium palma contour which is what I have and it shoots bug holes with factory 140's.
28" barrel that I carried in the deer woods in the heavy woods of SW MO and barrel length was not a problem.

 

[Rob01]

Re: 6.5 Creedmoor Build Input

Split the difference and go 26"

We use standard Kreiger 8 twist barrels and they work on the 120s and 140s very well. I am sure the 5R will too as Kreiger makes very nice barrels.
