I rebarreled a Bighorn action with PT&G bottom metal from 6.5 x 47 to 6.5 Creed. The Alpha magazines don't work well with the 6.5 Creed if I load 10 rounds. The sides swell to the point that I have to beat the magazine into the rifle. I have an AI 10 round 308 mag that might work if I keep playing with the lips but it is a bear to load 10 rounds into those mags. The skin on my thumb actually separated from under the nail after loading it four times. What mags work with this combination.
