7 saum in AW Mag


aam

Recommended Posts

I’ve just been asked a question by one of the club members which I do not

have an answer to.

 Do you know if the AW magazines can be used with magnum sized (SAUM family) cartridges?

Do the feed lips need adjusting or can they just be used as is?

Off the top of my head I'd say no..

AI mag is about 2.9 inches internal..

I think my saum loaded with a 184gr hybrid is 3.1 inches.

Mine run in a 300wm magazine and I've put a spacer at the back so the cartridge sit more forward

AICS Mags will run 7MM WSm Cartridges - Ive built several custom rifles in this cartridge wiung Short Action Magnum bolt face

 

The reamer is however specifically throated a little short, but still allows 168-180 class bullets to be used

If one removed the strengthener plate and re welds you have another .080" - .095" to play with to "follow" throat erosion....(should you wish to)

Its not the feed lips that will be the issue in a double stack AW mag...its the follower. Its cut for a 308 width case. The saum is fatter. You may get 2-3 in and feed, but it will always be dodgy. Altering the follower would work

The AW is longer internally than the AICS.
