What short action caliber?

Good evening all,

I'm looking to possible build a bolt rig from a spare axis action that I have on the bench. To meet requirements, the barrel will be around 17'' and I'm thinking of running a LSS chassis. I'm planning on running a Holland's brake as well. Barrel will be Shaw or Mcgowen.

The main area of use will be shooting targets (700 yards max) and deer out to 400 or so.

I'd like a 6.5x284 but I'm unsure if I can get the most out of this round in a short action due to seating depth restrictions as a repeater.

I'm contemplating a 260 AI, 6.5 Creedmore, 308, 7mm-08...

Anyone have any suggestions? I've got a spare long action as well, but it's attached to my 7mm STW, although I haven't used that rifle since 2013.

I've also considered a MOA as well, but that will take more time as I can't "pay as I go" (wife gets upset when I buy expensive toys)

Any help is appreciated.

Thanks,
Brenden

Is the brake included in the 17" of barrel length? I don't know that you'd miss a whole lot with the 260 AI relative to the 6.5/284 from a short tube, given your parameters. The 284 Win works in a Savage Striker mag so it may not even be an issue.

I have a long gun chambered in 6.5x284 Norma and it's a tack driver. It was, however, built on a long action. To get the most out of that caliber, you are probably going to have to load it long and use hardened lapua brass. I can tell you for a fact that I burnt out the first barrel at around 850 rounds. Every 100 rounds or so the throat eroded .002. So I played chase the lands with it. All that being said I still put a new barrel on with the same chamber specs. Retumbo gave me more velocity but 4831sc kept it very accurate and stable, but at lower velocities. If I were to do a 6.5 in a short barrel I would consider a 260 or 6.5 creed with 130 gr bergers or something similar.

.284 Win if you want expensive brass.
.260 Remington if you want cheap.

Ill probably end up running a 17" tube minus the brake. I'm still unsure, I'm in the planning stages at this point. I'd like to acquire a 6.5 though. I only own a 6.5x55 at the moment, and I'd like to try something else.

That and I'd like to play around with a different platform. I'm losing love for my encore.

Go with the McGowen barrel over the Shaw.
All of my McGowen's have shot great.
