MDT replied (replied quickly, to their credit) and said the mainspring needs to be worked pretty hard and it'll allow the extra rounds.
I took some empty cases, filled the mags. up, and forced the second from the last round down with a blunt edge and cranked (and I mean FORCED IT HARD) the last round in there. Going to let them sit for a few weeks as I know there's no way that first round coming off the top is going to be smooth at that pressure.
So bottom line for me is: 1) MDT mags. feed the 6 ARC round great, 2) mainspring needs to be compressed to take the force off it to get a smooth first round chambering.
