Grendel as a Universal Infantry Cartridge

[stanc]

Velocities for the Hornady loaded AMAX 123 out of my 28" barrel averaged 2720 FPS. From a 20" they averaged 2590. At 2590 they are still supersonic supposedly at 1223 FPS.

Velocities for the Scenar Factory load were 2740 and 2600 respectively. At 2600 they would be still supersonic at 1257 FPS.

Thanks for those numbers, Bill.

That said, I don't think either bullet is a real world bullet for military use...

No doubt about it.

...and some FMJ with a similar BC would be needed to carry that banner.

Trouble is, that doesn't seem possible. With the environmental laws prohibiting lead in bullets, it looks to me like to get a circa 0.54 BC with steel (or steel and copper) as core material would make a bullet with an impractical L/D ratio. Barnes' nicely-streamlined 110gr solid is about 4.7:1, and only has a 0.45 BC.

Make an eco-friendly FMJ or T3 bullet, with L/D of 5:1, and weight probably would not exceed 110gr. Which makes it seem likely that BC would be ~0.45, also.

On the subject of FMJs, what are the chances of you shooting the 120gr Normas (in 20" barrel) to 1000 yards?
