Johannes.St \Liandri-Innovation_RifleCompany/: 6.5Grendel is by far better and beats even 7.62x51 at 1000Meter, in energy, accuracy, less wind drift, better penetration shape. And high end 5.56x45 have similar bc to 6.8 while beeing much lighter with less recoil, more magazin capacity, less bolt wear. Technically a 5.56 bullet have the capability of having 90 grain. 6,8mm with such a short bullet and TERRIBLE ogive is just useless compared to 6.5 and 5.56.
jesusaragorn: peaches , pears , apples ... all compared with each other ?
James Campbell: What about the sig sauer m400 enhanced nato? Any complaints
America 2.0: This is why I want a .308! :)
Catalin Cata: 6.5x35 best
Molon Labe: Quit calling it assault rifles. It's just a rifle.
HardcoreAmericanUSA: 5.56 for fun / tactical situations for low recoil and penetration. .308 for hunting because of knock down power and you only need one shot. I dont know much about the 6.8 SPC so i do not know when that would be good. Either way, a bullets a bullet. If you know what your doing they are all lethal and its just a personal preference. Cool vid.
Robert Bowen: Agreed, they are all fantastic weapons but I still vote for 5.56. I love the way you can continually hit the target in such a small group. They are the light, and my wife has a shoulder problem and can fire the 5.56 without hurting herself. I would love to have all three if my retirement fixed income would allow though.
Danny Dingo: User preference? what about victims preference...I think victims choose the .223
R.C. L.: For hunting purposes, and no shots beyond 300 yards, would you recommend the 6.8 or .308? I have been debating a 6.8 build, but I'm concerned about knock-down power. Also debated the .308, but concerned about weight. Any help would be appreciated.
Southlander1000: All great platforms. I enjoyed watching this. It just reminds me that when I need real knockdown power (for elk and moose, etc), I go for my FN FAL. I used it on a deer with 165 gr. Hornady SST and it blew in one shoulder blade, through both lungs, and out the other shoulder blade at 125 yards. I decided I needed something with less over penetration value, so I ordered a DSArms ZM4 in .300 AAC Blackout. Can't wait to try it out -- with and without the can.
SmokeRingsPipeDreams: Someone found in K-Berg's house at night, will be found there in the morning!
michael malkowski: Try the 5.56 with something other than an FMJ round. Something that expands will give a much better impact. That being said, the 7.62x51 has double the muzzle energy of the 5.56 and is only going 300 fps slower with a bullet 130% heavier than the 5.56.
kenny johnson: Each round was designed for a different purpose You really can't do a legitimate comparison.
MrAristes: Thanks for the video! I have both a 5.56/.223 build and a 6.8 build near completion. I'm familiar with 5.56 but not 6.8. I can't wait to see what 6.8 is like. Entertaining video, really makes me want an AR-10 also. On a side note, I couldn't decide if your face reminds me more of Lou Ferrigno or Vitor Belfort so I've decided to think of you as Lou Belfort, friend of all 2A supporters:) Thanks!
justin milburn: 7.62
ariel4more: my opinion, the 6.8 is a great round. the 308 is a bit overkill, and the 223 is too small. Especially out of a shorter barrel. the 223 is a low pressure round, needing a slower burning powder, and a longer barrel to get its steam built up. the 6.8 can handle much higher chamber pressure, and perform great out of a close quarters designed weapon, and has a .270 diameter bullet vs a .223 diameter bullet to boot!!!
CPHannigan: Currently, the military has dropped all use of the 6.8 SPC. It is a great round within 400m, light recoil, accurate, reliable, and all around well designed. The only down fall is the logistical problem the cartridge presents to NATO. If the U.S. military switched to it, what would the rest of NATO do? I think it's best for us to stay with the 5.56 NATO for the time being.
Christopher Morris: The 6.8mm SPC is an excellent "in between" type of round. It's too bad that the military can't afford to upgrade all their rifles to this caliber. Is the military at least using this on a limited basis?
Robert Dorner: Think about making that new build a 6.8 and look at ARP. I went through same process as you. Got into shooting AR's in military then bought a 5.56. It is great, but, now building a 6.8 especially LWRC/Federal/ATK & Magpul got together. The 6.8x43 will be the next great thing. Then I build my 7.62x51 or .308 AR-10 or buy from Windham if a good price
