hs precision from 338 lapua for 260 remington, what magazine?

[zloe]

I've found a FCP HS Precision stock that was originally for a 338 lapua for a good price with the bottom metal. Wondering if anyone has experience turning this into a long action for shooting a 308/260/243 etc. I'm unsure what magazine to buy... would prefer a 10 round. Thanks.

someone has to have an opinion on this!

If the screw spacing is 5.062 you are g2g

Not sure about that one...I don't think there is a .308 "class" magazine that will fit .338 bottom metal. Different than a typical LA like a 7mag, .300 WM, etc. due to it's OAL. That's why it's easy to spot a .338 LM on the firing line from a mile away.

Confirm the pattern of the inlet/bottom metal (AICS standard?), then look for a .308 mag designed for it- I would be surprised if there is such an animal due to the length of the mag, and the much shorter follower that would be required. Darn near an inch difference in length between these rounds.

Then, you'd still need the "correct" receiver that's compatible with the .338 length mag- or have a LA receiver milled to accept it.

It's still early in the morning and maybe I've missed something here- but this is not a road that easily traveled, unless that stock is free I think you'll spend more trying to "get it to work" than just buying a LA receiver and stock (assuming you want to build the .260 on a LA).

Yes,thata the plan, long action for 260. Thanks for the reply and info.

You'll need a AICS 300WM mag that's been adjusted for use with 30-06. CDI had them available when I did my 6.5-06 back in 2015-2016.

If your HS Precision mag and bottom metal are the same as mine, it takes the longest AIC style mag offered - 3.850". Nobody that I am aware of makes a 30-06 sized mag to fit that length. My guess is that one of the Accurate Mag 3.850" long magazines might work for you - see what worked for me in the link below. As for a 10 round 3.850" long mag that would fit that bottom metal - I have never seen one in any caliber, but perhaps they do exist. It would have to be pretty tall to hold 10 rounds - something like 8"-9".

Possibly something in my thread about using multiple rounds in the Savage long actions with 3.850" length bottom metal might be helpful.
