| #8 Alexander claims that shooting a 123-grain Lapua Scenar with a ballistic coefficient of .547 and a muzzle velocity of 2,600 fps delivers outstanding accuracy out to 1,200 yards. But a hotter version of the old reliable .243 Winchester? Not hardly. I used to pick up free M-14 brass at the range, neck it down to .243 dia. and fire them at about 3900 ft./sec. (with an off the shelf Remington model 700). Killing a deer at 475 yards, to me, is at least believable. But Alexander with a custom made target rifle with a 28 inch barrel, and custom everything, cannot even push his muzzle velocity past 2800 ft./sec. For Alexander to claim that the 6.5mm Grendel is a long range target round, (in AR anything), is to me, nothing more than a good reason for spewed coffee. Granted the 6PPC is the premiere target round in the world for ranges up to 200 yds. But it falls off dramatically after 250 yds. Alexander has struggled to even match the the ballistics of the 6PPC. The U.S. military has insisted for years that the 5.56 NATO has more than enough bullet energy for close combat and enough energy, out to 400 meters, to take any combatant off the field of battle. With less than 1875 ft/lbs. of muzzle energy and reputed problems loading both magizine and belt fed weapons, I find it hard to believe the military could justify adopting the 6.5mm Grendel round. Factory muzzle velocity: 2620 fps. Factory muzzle energy: 1875 ft/lbs. Factory recomended uses: Competition, Target Shooting. |

| #7 "I killed a buck at 475 yards with a 100 grain .243" good shooting :-) |

| #6 The Ordinance guys love commonality. Yep, take an inferior cartridge and create three inferior weapons. You have to love it. These are the same guys that replaced the .45 ACP with that popgun 9mm and now are buying .45ACP again. So why not go back to the .30 or move to the .243? |

| #5 There are two problems with the 6.5 mm Grendel. One problem is that it requires major changes on belt fed weapons to get it to feed. It has a real long neck and a quite short base. Army Ordnance doesn't want that expense and while the round works fine in the magazine fed AR, the military wants commonality with the least expense possible for the various belt fed weapons that use the 5.56 round. The other problem is named Alexander and his rather high licensing fees and prickly personality. |

| #4 The 6.5 is essentially a hotter version of the old reliable .243 Winchester round I hunted whitetails with back in Texas... I killed a buck at 475 yards with a 100 grain .243...I suppose you could hop up the .243 and make it a flat shooting beast. I kinda like this idea... |

| #3 12 GA Slug should be fine. |

| #2 Jeez, what is that, a 28" barrel? |

| #1 I wonder how many of these it would take to destroy an extra high voltage transformer. Or would a simpler muzzle loading .50 cal slug available at Walmart do the job? |
