Getting a trg 22 rebarreled. I am pretty sure I want to go with 260. Would the 6.5 creedmore be better? Longer mag seems to favor the 260 and factory ammo maybe better for the creedmore. 6.5x47 is wasted in the longer mag. Is my logic sound or am I missing something? Just making sure before I send stuff off.

I think you'll be fine with either cartridge. I went with the Creedmoor and do not regret it. The factory ammo is .5MOA capable which is a huge plus if you are not going to be relaoding and if you do reload, Hornady posts the load data on the box so you can just reproduce the factory ammo.

I'm going with the Creedmoor. It's a bit better case design, especially for a short action. The capacity is realistically about the same, but I like the steeper shoulder of the Creedmoor.

x47 and never look back.



Each member will have a different opinion.

Each choice has its pros.

260, you can reform your current brass.

CM, you can use published factory load data.

x47, you can wear out a bbl with only 100-200 rounds of brass since you can reload them more times than you can count.

Do you reload? I do so Im planning on going the 260 route when the time comes.

every diagram I have seen shows the shoulder to 30* on both. Is this incorrect?

The 260 is made to kill whitetails, the 6.5x47 and 6.5 Creedmoor are made to shoot accuratly.

The 6.5x47 gets to use all the magazine for very long VLD bullets.

I went with the Lapua cartridge and love it.

Reloading is mandatory.

Re: TRG 22... Which 6.5 rebarrel?

The only reason I will steer you away from the 6.5x47L is because of primer piercing issues with rifles such as the Sako and AI. Unless you plan on having the firing pin hole bushed you should stick with the 260 or creedmoor. Zak Smith experienced issues with the AI and it carries over to other military bolt rifles like the Sako. The facts are on page 3 of this article, but I encourage you to read the entire thing. Also, Lapua brass is available for 260 as well, so that may factor into your decision.

I think you have your wires crossed. It has been a while since I read the write up but the 260 and maybe the 6.5 creedmore had piercing problems due to the orginal mission design of the ai. This was a concern for me until eurooptics had sako build them trg in 260. The x47 did not have a piercing problem because it was run in a tube gun so custom action and it uses small rifle primers so they can handle pressure better.

It's common to have primer flow with x47L with normal pressures. Bushing the bolt is highly recommended!

I think I'd do 260 in the TRG since there is plenty of room to seat the bullet out further.

Well i just reread the article and he pierced primers with the 260 in the ai, had no problems with the x47 in the ai and the Creedmoor was the tube gun.

.260 is 20*, Creedmoor is 30*. Most of the Ackley improved cartridges have a 40* shoulder, and are known to get better velocity and the brass doesn't grow as much. The Creedmoor is halfway there.

Fair enough. I thought you were comparing the 6.5L and the Creedmoor <span style="font-weight: bold"> </span> . Going crazy researching the two...

I just did a trg-22 in 6.5 creedmooor and it shot the factory 140amax .417 @ 100yds consistently. I ran it last weekend, it was flawless! Velocity with my 142 matrix hand loads 2789fps.

He did have problems with the 47. While he did have issues with the 260 it was with hot loads. To get the same velocity out of the 47 you have to run higher pressures which means that the 47 is handicapped in these rifles because of the primer issue. I have copied the passage from page 3 out of the article for those that missed it:

"It was almost immediately clear that the pressure limiter in 6.5x47 in the AI-AW rifle would be the primer piercing issue I originally saw with the .260."

And then, he listed the following as one of the cons:

"To achieve same ballistics as 260, needs to run at high pressure"

If you run at higher pressures you risk piercing primers frequently. So, you run them at equal pressure and the 260 will outperform the 47 by 150 fps or more.

No wires crossed here.

My bad. Was quoting from memory and then skimmed article on phone at a break at work. I never really considered x47 from the start. It seems with that longer mag of the sako is wasted with the smaller case of the x47. I know there isnt a wrong answer with either the 6.5 creedmoor or the 260. I just feel for what I have tied up in the project I want to be 110% sure.

No worries. The creedmoor will let you chase the lands a bit longer, but I don't think there is a wrong answer between 260 and the creed. Definitely let us know the results - my TRG's barrel is getting long in the tooth.

This rifle is now mine, and I reccommend the 6.5 Creedmoor. Overall, I think you can't go wrong with any of your 3 choices. Any of them will be just fine
