using a short action cartridge in a long action ?

[buggz]

Is it bad to use a long action and then use a barrel/chamber for a short action cartridge?
I will probably guess reloaders do it for freebore and really long bullets?
Just pondering what my next action purchase might be...

I did 7mm saum and 7 max. Short action cals but ran them in long action. More free bore and mag feed. No issues for me when I had those cals

Not at all. It’s pretty common and even preferred to run Short Action Magnums in long actions. Allows you to run the longer heavier high BC bullets and still fit them In your magazine without having to seat them so deep you take up case capacity. Keeps from having to single load them

In fact, it's common enough that Tikka streamlined their manufacturing by using the same long action for all their rifles. Only change is the bottom metal for the various magazines and bolt stop.

It’s common enough the primary us army sniper rifle for the last 20+ was a 308 long action. Even @THEIS is doing it

Yup, and still can’t get 300wsm to feed right.

I had issues with the 6.5 PRC in a long action with AICS Mags but I believe that was more due to stock fitment than anything else. It would feed the stuff loaded over 3” but shorter would leave it unsupported just long enough to nose dive into the front of the feed ramp.

To prevent this issue I picked up some of the LRI mag spacers with the feed ramp in the front. Solved the issue entirely.

MAGAZINE FILLER BLOCK FOR SA MAGNUM CARTRIDGES

This solves the fundamental feeding challenges associated with running LA magazines loaded with SA magnum type cartridges such as the 6.5mm PRC/6.5MM RSAUM. These are made specifically for magazines produced by MDT and Accuracy International. They function the same, the difference is the...

If savage did it, you can too!

I have an old 112 (long action bull barrel) that runs 22-250. Works just fine.

Hi,

Shit, we are doing it in Lapua Magnum sized systems, lol

I attempted it. 6.5 SAUM, 700 Long Action. Magpul AICS mags. Worked really well.

Thanks for all the information and replies!

What are the bad things from using small cartridges in a long action?
Feed problems, and?

 

[buggz]

Say I put a 6.5CM SA prefit on a long action.
Bad?
Or, can I even do that?

 

[buggz]

Not trying to drag this out.
I am asking really in general, not trying to be specific.

If you have a long action, and you put on a proper short action cartridge chambered barrel,
what would be the downside consequences of doing so?

Thanks, great answer and information.

Why? Just wondering, and asking before I a make a wrong decision.

Thanks again.

I would only do the saum based or wsm or prc case on the long action. Get more performance and mag feed nice
