Aic aw mag issues. How to tune?

This past year I built a 6.5x47 on a defiance action. I originally bought alpha mags and had to modify them to get them to feed half ass. I’ve been shooting PRs club matches and doing good considering I only get off 80% of my shoots do to feed problems. I recently bought AW mags because supposably there the best feeding mag in the world. . I’m not sure if my problems are do to the shorter 47 length or vodoo but I just want a mag that will let me feed 95% of the time with out jamming. Here’s the problem I have with the aw mags attached in the pic. The ass end of the round is to low for the bolt to pick up. Any suggestions on how to fix or better yet I mag that I can buy that I don’t have to tune? Getting frustration spending hundreds and still have to single feed at matches to get buy.

AW mags are 'double stack, double feed', giving them an overall smaller size. The action needs to be specifically cut (feed ramp) for AW mags to work properly, and even then I've read/seen 'issues' with reliable feeding...

If you're 'pot committed' to those mags, maybe you could have a qualified smith see what's the "hang up". But.... I'd sooner sell 'em and run AICS (double stack, single feed) mags. My 6x47L runs like greased goose poop from AICS mags...
 
double stack magazines are usually built around a traditional case taper. if you load them with a straighter walled case, they normally get pinched at the shoulder. if you unload the magazine you can see exactly where the shoulder rubs. the paint on the inside will be rubbed off right where the shoulder sits. this could be a problem with a dbm as modifying the mag to feed would probably cause the magazine to not fit. on a bdl box i have had great success opening the pinch point up so the magazine wall runs parallel to the cartridge. ackleys and creedmoors feed this way out of a standard 308 box. normally they give me fits.
 
Brownells sells a mag lip adjustment tool, which provides more consistent spacing than using pliers. Also the spacing specs for a number of rounds is included. Surprising how much a few thou affects performance.

I've fixed this exact issue before. Just pull the spring and follower out of the mag by tipping it and twisting it out the front half of the opening. Then bend the follower spring so that it both puts more tension on the follower AND twist/bend it so that it wants to push the back half of the follower upwards (ie bend it so that it's a bit nose down).

That plus bending feed lips should get you in the right direction. On bending feedlips I try to open them up to the point that they present more of the case head to the bolt face, and get closer to the outside edge of the AW cut in your action. On mine the feed lips almost exactly follow outside cut of the action, and require the mag to be pressed firmly into the mag well to latch in place. The tool I used for bending feed lips was the one from Masterpiece Arms.

AW mags have been the smoothest feeding and most trouble free I've used thus far.
 
Sheldon N,

This is good info and that is exactly how I fixed it. Thanks for taking time to share this. Running like a champ now.
