Looks Like The Army Dropped The New 7.62 Rifle Program

[warboar_21]

Hmmm, 6.5 grendel is basically a 7.62x39 necked down, funny how "militarily popular" that round has proven its short stubby self to be. Works quite well in SKS, AK, RPD and RPK platforms.

The Grendel has minimum body taper while the x39 has plenty.
The Grendel is a great round but needs barrel length to achieve its potential.
The Army won’t go back to the M16 sized rifle anytime soon. The only way they could get max potential from the Grendel is if they adopted a Bullpup platform. We all know that’s not going to happen.

Don't forget that the Grendel is ideal OAL with about a 123 grain bullet. The military needs various bullet weights and lengths so the Grendel isn't going to work out of a AR15 size magazine, so bullets would have to be deep seated. The same problem with the 5.56 currently.

The 6.5 Grendel really is not enough of an improvement over the 5.56 with 77gr OTM or M855A1 in the barrel lengths they will be shooting it out of IMO. It will carry more energy down range than the 77gr 5.56 but it is not going to mean a whole lot. Don't expect the 6.5 to do as well with hard target penetration either. Frankly the .224 valkyrie with a 90gr or 100gr bullet would be better than both IMO. Problem is the .224 like the 6.5 likes the longer tubes. The .224valk with a 90gr bullet out of a 20" barrel can stay supersonic past 1000 yds. But all the current .224" bullets they using could be used in the .224valk also. The 7.63x39 really is no improvement on the 5.56, especially hard targets. What you gain in down range energy you lose in effective range, hard target penetration, among other things. Not to mention the platform they are currently using does not really care for the rather steep case taper.(mostly magazine issues) Might as well go with a .300blk if you want an anemic .30 cal cartridge, but that brings its own issues. What it boils down to is you will never get one round or one rifle to do everything well. I just wish people would realize that.
