I just measured the MDT short action AICS magazine with the idea I would restock my Savage 12 FV 6.5mm Creedmoor.
Turns out the mag only has 2.832 inches of internal space so I presume that would mean that rounds couldn't be seated out longer than 2.830 so there would be a bit of space to keep the tips from binding in the mag.
That puts some serious limits on the loads that have performed the best.
Most of the reloads that were the most accurate are over 2.832 O.A.L.

Anyone know of another short action AICS mag that allows another 0.025 in internal length?
