CMMG 6.5 Grendel VS 5.56 | Which One Is Better?

[Music] which one's better 556 or 65 grendel today on precision rifle network [Music] all right guys so what i've got here is two almost identical guns from cmmg both in their their resolute line the 200 series except this one is chambered in five five six and this one is chambered in six five grendel what i'd like to do is just kind of compare and contrast and figure out which caliber which rifle would be would be good for what type of a roll or a function and maybe help you guys figure out which one you might like to go with if you could only have one if you can have one of each pick up one of each they're great rifles but we're just going to kind of get them out to um realistic distances for the way that each rifle is set up and show you what they can do that's what we're doing today let's get started all right guys what we're doing here to start out with is i've got the 556 and this has been previously zeroed at 36 yards kind of the marine corps zero i know they probably did it in meters yards is close enough it still works guys so don't give me a hard time for that did a previous video on it i'll link it up above but or down below but basically you zero a standard 556 at 36 yards and then if you look at the ballistic drop chart you know it kind of climbs and it comes back down right where the two cross are equal zeros and that happens to be 300 yards if you zero at 36 yards so what i'm doing right now is i'm going to go ahead and just go straight out to 300 yards with the 556 and see if i can get some impacts on the steel down there and then i'll be switching to the e65 grendel and i want to show you some uh weaponized math from frank galle and sniper's hide and mark taylor and we'll get the grendel out on steel as well [Applause] [Music] there's 300 [Music] there's 300 300 [Music] 300 so 36 and 300 guys the zero works especially for a standard ar with a red dot just a quick little pro tip you might have to reduce the brightness of your red dat all the way down to where you can just barely see it otherwise you know the the red dot in here is completely covering your target downrange now if it's a man-sized target obviously different but this is zeroed it hits no problem point of aim point of impact at 300 yards uh and all the way in you know within just a couple of inches so uh this one is good to go let's switch over to the grendel all right guys so here's the deal i went ahead and got my uh zero done on the grendel i hadn't set this rifle up yet and i zeroed uh with the with two shots and then uh two more shots trying to figure it out you'll see on the the group that i post for you uh which is typically what i do i fire one i see where it's at i fire another one to see if it's actually there and then i make my adjustments in scope so you'll see a couple of groups on there that are two shot groups and then there's a five shot group for the accuracy of the grendel and as you can see it's about you know three quarters of an inch at a hundred yards so as i start stretching this guy out in distance i've got 500 yards to deal with today which is perfect for a grendel we're going to talk a little bit more about the useful distances for those but you can gather your dope just using this card and weaponized math because what they've done is they've doped gravity doesn't matter the bullet doesn't matter the weight doesn't matter how fast it's going gravity pulls at the exact same rate hopefully we can all agree on that so this chart is all about doping gravity and it's super super helpful right all right guys while we're waiting for that 6'5 grendel to cool down a little bit so we can stretch it out to the 4 and 500 yard distances i thought we'd just talk about quickly what is the 556 good for right this is not a long range platform can we agree with the way that it's set up right no bipod no magnified optic kind of cheap plinking rounds which is what the vast majority of shooters are going to be using this is set up the way that the vast majority of people are going to be setting up their rifles right so this might be good for um for home defense it might be good for you know plinking targets at the range at say 100 200 maybe 300 yards so really good for uh hunting uh big critters inside of that distance fleshy type critters that are big you know shapes like this really good for that you got to be able to to shoot them standing off hand you got to be able to just kind of run up and support them against a tree you gotta you know those are the types of things that an ar like this is good for right so 100 yards right so all day long at 100 yards uh with it like that i'm not going to try and take a standing offhand 200 or 300 yard shot but you get the idea those are the types of distances that a setup like this is good for you know the cmmg is a really nice reliable weapon system 16 inch you know standard length barrels with the muzzle brakes you've got their their rip stock which is super simple and easy to adjust most people will run it all the way out for any kind of in more precise shots you might tuck it in tight if you're trying to stay real compact for clearing your home or operating inside of around a vehicle those sorts of things but you can quickly rip it out there obviously you take any type of 223 556 style magazines throw a good red dot on top like this crimson trace and you're good to go we got our impacts at 300 so going out to 400 we're gonna need 6.5 moa of elevation uh to be on at our 400 yard target so i'm gonna dial up six and a half and we'll see what we get on our wind it uh is pretty switchy down there today [Music] [Applause] [Applause] [Applause] [Music] all right looks like we need about one more moa to true that up let me check again i'll give it a half so instead of 6.5 we were seven at 400 yards so looking at our uh our math here need the equivalent of three mills at five so looking at my conversion here coming down my mills line to three mils we're going to need 10.25 moa at 500. there's ten two five at five hundred and our wind was switchy down there so again we're gonna be lucky to get this but we're gonna try it anyway as our impact on the water line impact water line we actually needed 12 out there so we're going to come up to 12 moa so now just using the chart the weaponized math and roughly 10 rounds we have effectively doped the 6'5 grendel out to 500 yards having no previous data about the speed or or anything so now let's talk briefly about what the 65 grendel would be good for right we're going to throw a bipod on a gun like this right we're going to throw a magnified optic on a gun like this we're going to run a rear bag because we're trying to be more precise i've taken a couple of different designated marksman rifle classes and you know the dmr type role is everything from you know precise prone shots like a law enforcement sniper might take at 100 yards or less 200 yards prone something like that but most of it is positional right it's going to be off of a car window it's going to be off of a a a modified prone type position it's going to be you know on a on it with this caliber it could be a deer off of a tree branch the kinds of stuff we find in prs nrl style competition is right in line with a designated marksman type role it's just an ar platform in a more efficient cartridge that you want to be more precise with that really is all there is to it now the cmmg this is the resolute the 200 series in 6.5 grendel and it again it's got a an 18 inch barrel it's it's well built to handle these specific types of rolls in these conditions and handle it quite well you saw the accuracy of the gun three quarter moa at 100 yards so as long as the shooter is doing their part it's extremely capable and as we look at the ballistics here you can see that the drop data still retains a good amount of energy at 500 600 yards for the grendel definitely better than the 5.56 so it would make a much better deer cartridge and a much better mann cartridge out at those slightly further distances as opposed to the 5.56 so again the cmmg resolute the 200 series these guys are great to work with an awesome company they loaned me this rifle for the test i actually own the 556 version you know one of the the cool features about this gun is the the rip stock it's still got a button on the back where you can adjust but simply just put pressure onto the rear and you can pull this stock out it's a very nice quick feature you've got an oversized ambidextrous charging handle which is nice ambidextrous controls all the way around completely free floated you've got a brake up front really good system guys and you can check out their website for more information but i've been really impressed with it so far in pack [Music] impact [Music] as you can see guys no issues whatsoever with that setup if you've got an ar setup like this with a red dot eotech whatever it might be highly recommend that marine corps zero that 36 and 300 yards zero because you're effective then on man sized targets and even deer all the way in and through that range right if you need to be more precise you need a little more energy for those longer distance shots say up to 600 yards 6'5 grendel might be an absolutely stellar choice for that so hopefully this helps you a little bit today guys thanks for watching precision rifle network tune in again soon for more great videos [Music] you
