New Cartridge Developments and Implications for Dismounted Infantry Soldiers

[pinzgauer]

As far as brass and bullets go, the new Hornady brass seems to be going through some teething issues when it comes to fitting in certain chambers

Hmmm, only chambers from mfg's that chose to differ from the published standard. Which for a service rifle would be a non-issue. IE: super Tight chambers with minimal headspace are big problems for reliability. it would be addressed by now, except that the same mfg's then argue with folks who try to get it addressed. Looks like CSS is finally fixing barrels, but that whole saga is not a grendel cartridge issue, nor hornady brass. It's a mfg issue with a subset of mfg's.
