AI CIP mags VS. Standard AI MAGS

Hey guys. I'm wondering what the difference is between the Accuracy International CIP mags and the regular Accuracy International mags? Thanks guys.

BTT - I have the same question...

Deals with length. CP mags you can load to a longer OAL. 3.60" is all your gonna get with stardard mags and that probably won't feed reliably Everytime if loaded that far out in a stardard mag. If your shooting a long action and loading long go with CP mags or do what I did and don't even run AICS. Go with accurate mag 3.774" length mag. But only two manufacturers produce bottom metal for it. Accurate mag has their own which is a little pricey or give Dave Kiff a call out at PT&G, pacific tool and gauge, and let him know what your shooting, how far, and how you intend to load it, long or short. FYI it's a total drop-in too! No in letting required.

Thanks for the info! Any issues with the vertical rib interfering with loaded (or loading) rounds? I'm currently researching a 338 EDGE build and that seems to be an issue for that caliber.

M1A,
I would be cautious about an edge especially with a 300 Berger loaded to 3.7 or so. I use a Wyatt's extended box and mine are loaded to almost 4.000.

Cautious in what way? Is 3.7" getting too short for the 300gr bullets? I seem to remember 3.785" being somebody's OAL for the EDGE but I can't find that now...

That's Carlock's OAL with the SMK. I also used the same OAL with much success.

I personally have not had good luck with the long bullets seated deep in cases. One caliber had erratic pressure. High ES and crappy groups. Just throwing my 1/2 cent of advice. Not trying to start any arguments.

OK, that's what I would expect with the larger bullets. I just wanted to make sure I wasn't overlooking something. Thanks!
