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?
