Grendel as a Universal Infantry Cartridge

[Tony Williams]

I am not sure what can be done with a 6.5mm bullet that hasn't already been done or that would cost so much money to produce that it would bankrupt the nation. The bullet has been around for over a hundred years and has been thoroughly developed in terms of military, hunting, and competitive shooting. Unless you develop a powder that produces greater than 50% higher velocity with a 50% reduction in pressure, you won't get the speeds out of a 30 grain capacity 6.5mm cartridge that will allow it to compete with a 5.56 or 7.62 that doesn't need any more development.

The last time a 6.5mm military ball bullet was introduced was I believe in 1941 for the 6.5x55. Before that came the Japanese Arisaka Type 38 in 1905. A lot has happened since then - you only need to look at the M855A1 EPR.

Who said anything about a 30 grain capacity limit?
