Long Action Receiver for Short Action Caliber?

[SN13]

Can you effectively use a Long Action receiver for a short action caliber?

Like a LA 30.06 action but for a .308 barrel/ammo?

Or is this really a bad idea?

 

[Supersubes]

The m24 did exactly that.

 

[Steel head]

The m24 did exactly that.

You could load 308, 7mm-08 and 260 extra long and get the benefits it can provide.

I'm building a 7 SAUM on a Defiance XM so I can load a little longer than short action length. 175 Berger..heel just above the shoulder neck junction @ about 3.05" COL.

 

[Powder_Burns]

Always thought this would be a no-brainer for loading long for caliber bullets and retaining repeater functionality.
This would also let you chase the lands and still fit a box mag for a longer time between chamber setbacks, if thats your thing.

If I'm using a control feed like TL3 would it be even easier?

 

[Powder_Burns]

Yeah, push feed could make for feed issues...controlled round feed probably the preferred method for this scenario.

What are you trying to accomplish exactly?

Building a 6.5 CM that i can change into something bigger later without having to buy ANOTHER $1300 receiver?

 

[B y r o n]

If I remember correctly, the 6.5-284 was a perfect fit for the long action.

 

[SN13]

I'm hoping one day to upgrade to something longer range later. like a 280 or something.

I just want to know if there are any red flags running a 6.5CM in a TL3 Long Action for now?

Thanks guys.

@SN13 there is zero issues. I use a tl3 long action to shoot 6 dasher without issue.

 

[SN13]

Awesome! thanks. I'll go LA then!

what magazine do you use?

 

[SN13]

what magazine do you use?

I haven't built it yet. I can use whatever magazine i need to. What would you recommend?

My PLAN was:

KRG Bravo Chassis
TL3 LA

And then customize the Chassis after that... I'm just not a fan of the skeletonized stocks.

What mag options would that leave me with?

Thansk!

Oh i think @Supersubes was asking YOU what magazine you use.

Sorry about that SN13, I see now it grabbed both posts.

 

[SN13]

Paging @Maurygold We need to know what Mags you use in your 700 LA (or custom) that you shoot 6 dasher with.

Thanks!

Using a manners mini chassis with aics magazine. I don’t have any problems with the nose diving some people complain of but I did play with the feed lips just a bit. If I hadn’t of gotten to work with just that I would have put the primal rights follower s/a kit and tried to modify it a little to work with l/a

FYI,
the Magpul 30.06 mags are great for feeding your LA. I have a 308 on a long action, for mag feeding the longest .30cal bullets around, and love these Magpul mags - they work great, are tough as heck and don't cost much.

I run several of what you speak, on Tikka T3 actions. While they may not be big ole LA actions, they are certainly bigger than a SA or XM. Right now I currently run a 243win barrel on a 30-06 action and a 25SAUM on a 300WM action. no real problems, both feed fine from LA tikka mags, just gotta swap out the SA bolt stop for a LA and you're set. Makes it nice so you can simply change the bolt stop and have a more potent cartridge if the task at hand needs it.

 

[SN13]

Well Thanks to everyone, i just bought a TL3 Long Action, Standard Bolt Face.

The wait begins. Gonna be my first "Built" bolt action.

This thread has been very informative! thanks all!

I have a 284 so kind of in between length but it’s built on a crf long action and I have never had a feed issue (I use a win mag aics magazine). It offers the benefit of increased load length and speed for higher bc for cartridge. So for example I run the 284 at 3.225” and can safely get 2800-2900 FPS with 180 eldm.

Awesome. having the option of running Short Calibers LONG as well as some LONGER calibers if need be, is what I was after.
