Grendel as a Universal Infantry Cartridge

[JASmith]

One of the challenges we have discussed has been our perceived imperative to use 'green' ammunition. This translates to copper and iron as the primary components of the bullet, making the bullets longer than would be the case with traditional lead-copper bullet construction. A military cartridge also needs to have a tracer round variant with the attendant increase in bullet length pyro compounds are usually less dense than iron.

This development may serve to both minimize the adverse bullet length impact and to keep ball and tracer rounds on the same trajectory because one outcome of this effort may be that all ball ammunition is tracer ammunition:
