7prc AICS mag?

the standard length 3.715 magazines allow plenty of room for the 7 PRC. This is a photo a buddy texted me of his with a factory precision hunter 175eldx load.

Is this the 300WM or the 300 RUM 3.715 OAL mag?

Great to know and see the 3.715 mags will work great for 7 PRC

The Oryx chassis in long Howa 1500 in 6.5PRC uses the 3.715" also.

When I had my 7 prc it fed fine even from the cip length mags.

3.560 works fine as well

In building a 7-300 PRC can you use the same magnum long action and magazines for 7 PRC, 300 PRC and 7-300 PRC in the same rifle and just swap out the barrel? The 7mm PRC's action requires a 0.535" long action magnum bolt face, will that work with the 300 PRC and 7-300 PRC? I ask because I'd like to build a rifle that can fire different cartridges with just a barrel swap in a XLR 4.0 magnesium chassis.

Will the 6.5 PRC mag work for the 7 PRC? I am also using a Oryx chassis. The folks at MDT told me I would need to use a 300 WM magazine.

No it will not. Too short for 7 prc
