Looking for recommendations how tune MDT 6br mags. .
I'm using MPA Chassis, Terminus Zeus actions, MDT "BR" mags and AI AICS with MDT BR/Dasher Follower kits;
I think MDT BR mags need a "stronger" follower spring.
No comparison to AICS MDT (actually PVA I think) BR Follower Kit spring as far as nose-up pressure on follower and rounds.
Tip I was given that works well is to always put some graphite powder in new mags to lubricate follower travel - makes a huge difference in follower binding in my experience.
Also, check COAL. MDT lists possible of appx 2.500" but if my cartridges are near COAL 2.500" about 7/8th round nose dives as mentioned in OP
