Follower differences - 5.56, 6.5, 6.8

Do 6.5 Grendel and 6.8 SPC still run well with 5.56 Magpul followers? I have seen pictures comparing, I believe, PRI and Barret 6.8 SPC magazines and the bullets were held at different heights and such. Are there followers specific to 6.8 SPC and 6.5 Grendel that perform better than Magpul Gen II anti-tilts?

I'm not an expert but i am not sure how well they would run with 223 followers.

Yes the Barret 6.8 mags hold the round a lil higher than the PRI mags

Are they held higher because of the follower, or perhaps the feed lips?

I don't belive that it would matter, 5.56 followers wouldn't fit in a 6.? mag, and all 6.? mags already have the anti tilt followers in them. You could probobly get 4-5 6.? rounds into a 5.56 mag before it would bend out of shape.
