Grendel as a Universal Infantry Cartridge

[JASmith]

Thanks! That helps me visualize things a bit better.

And, yes, staggering the stacks does indeed complicate assessments of magazine length, numbers of cartridges, and so on.

Another way interpreting the stack height and magazine thickness might then be that the differences in dimensions of a 30 round magazine will be effectively negligible. Further, the difference in brass weight between the stretched Grendel and the stretch Grendel may also be as close.
