Alternative to 6.5 Grendel?

[320pf]

All my experiences with M855 on human tissue have been very consistent:

Avulsive tissue destruction, larger-than-normal wounds with grotesque characteristics, life-changing or life-ending terminal performance.

The constant mantra that 5.56 doesn't cut it seems to come from people who have yet to see what it actually does, but won't let this argument alone for whatever reasons.I think we would have been fine with .222 Remington case length, shoulder blown forward with a 30 degree angle, and left it at 1.700", giving us another .060" of OAL.

Do you mean something like this?

From a 16.5 inch barrel, here are the typical velocities that you get with the 25-223Ar cartridge.

Horn 75g VMAX (BC= 0.290) 2900-3000 fps (1400-1498 ft-lbs)
Barnes 80g TTSX (BC= 0.316) 2800-2850 fps (1392-1442 ft-lbs)
Nos. 85g Bal. Tip (BC= 0.329) 2750-2800 fps (1427-1479 ft-lbs)
Speer 87g TNT (BC= 0.310) 2750-2800 fps (1461-1514 ft-lbs)
Sierra 90 BK (BC= 0.37*) 2650-2700 fps (1403-1457 ft-lbs)
Speer/Sierra 100 g SBT (BC= 0.393** 2550-2600 fps (1444-1501 ft-lbs)

*Sierra Bullets lists variable BC's
**Speer lists 0.393 as the BC for their SBT bullets. The form/shape for the Speer and Sierra bullets are nearly indistinguishable.

The 25-223Ar can run the Grendel out at distance. Here is a link to several ground squirrel kill out a 721 yrds
