6x47L binding in 12rnd MDT mag

[Loe]

I recently switched from 6.5 creed to 6x47L. I have two MDT 12 round mags one brand new and one 6 months old. They feed the creed perfectly and no binding issues what so ever. After I switched to 6x47L the rounds bind (on the case) in the mag and fail to elevate to the top. For the life of me I can’t seem to figure it out and have had to use magpul aics mags instead (that work perfectly) anyone experience this or have an idea why it’s happening? Maybe a spacer kit?

Clean the mags , and make sure the follower doesn't have any edges catching some sandpaper or a file work good.
If not accumags worked good in my 47.
AI mags also without binder plate

These don’t have binder plates, I’ve also been over these. I’ve noticed with the mdt mags (being wider) the 6x47 brass seems to bind on the front case guide on the mag body. Moving the case forward in the mag it rides on the guide and not behind it. I made a spacer to test this theory and it feeds and elevates all 12 rounds.

hmmm. Not sure. I’m using AIAW mags with my 6x47. Had to tweak the feed lips a bit since then haven’t had a problem.

The mdt 12rdmags don't get along with the x47 case. The case taper pushes the rounds against the walls of the mag, cause them to not move upward IOT feed.

I just found this out from a friend, the spacer I put in the back seems to work perfectly, makes it so the case has to ride on the guide and not bind behind it.
