lots of packs will have a harder time holding the higher capacity pods.
I know my LYSK pack will do it, but I have to put some effort in closing it down and sometimes it slides down the the last magnet (2 are made to hold the pods in place).
Empires shouldn't have any problems, nor DYE (obviously
), PE/NXe, or Criticals.
idk about the redz, hybrid and lesser brand packs... or the SLYs, albeit the SLY packs I've used already seemed tight on the average 140 round pods.
