After having this discussion with someone else on here. And testing the one I had to see it did clear. I grabbed a brand new out of the cabinet. I forced the mag up into the mag well, then I ran the handle up and down and let the bolt fluting remove material. It went from binding with pressure on the mag, to no problems across, 5 manner mini chassis, 2 pillar bedded manners stocks{PTG metal}, and a pillar bedded greyboe{mesa bottom metal}. I did this to a brand new mag, because the one I was using had already worn in and cleared with pressure on the mag without me ever noticing the clearance issue. I had run about 1400 rounds of 22-250 about the same in 6.5 creed and about 400 243AI through that one. If you have an AW mag cut action it is not going to work, there is nothing to stop the mags from going too high up in the action. I would like to see one of these mags that can't be made to work. You have to get pretty high up on the bolt nose before its wider than the case.
Here is a picture of one with the offending material removed. I don't have anything against accurate or AI mags. I have a cabinet full of them. Things are rarely completely true or untrue with aftermarket part fitment.
