CMMG 6.5 Grendel VS 5.56 | Which One Is Better?

*My mistake – this grendel is in the 300 series from CMMG.
THE CHART – go to the Sniper’s Hide forum and search for Weaponized Math. You’ll find it there.

Where can I find that ballistic chart?

I spent 22 years using 5.56 with fixed sights with no problem hitting 300 meter targets.
This Grendel caliber with a scope is just amazing. A definite advantage.
I only have access to a 500 meter range but I can tell you that very little math or skill is needed
to get center mass hits at 500 meters and maybe more.

Just found your channel, GTG

6.5 Every day 2 x the weight, long range accuracy , boy silly question ! I'll be using a Grendel and a 6.5×55 to attempt the 1km milkjug challenge

Awesome caliber, use it for piggys and deer.

.223/5.56 from 16" barrel has no trouble hitting a full sized silhouette target at 500 yards with iron sights. But gotta love the 3x energy delivery a 123gr 6.5 Grendel bullet can land at that 500 yard distance!!!

“Big fleshy critters like this” 😂 – awesome rifles and thanks for the video!

6.8 SPC…..

224 AR is better than both… A 224 that uses a grendel case… It shoot a 90 smks with .55 bc at 2950…. A real marksman rifle…

We have a solid amount of field data on the 6.5Grendel with wild game. For wild game we pretty much exclusively shoot the factory Hornady 123gr SST and a majority of the time use a 24" barreled set up because thats what the box data is based on as they use a 24" test barrel for that so its a fast conversion in the field when we need to. I have killed 1x Elk with a 18" barreled upper at 200yds (head shot) and 3 Antelope with the same upper within 200yds as well. The 24" barreled upper has killed 7+/- Elk, 3x Ibex, 2x Barbary Sheep, 1x White Tail, 1x Mtn Lion, 1x Javelina from 150yds to 480yds. My 15yr old son shot a Cow Elk at 480yds (one shot kill – neck shot) for the longest stretch out of the 6.5Grendel, one Ibex was at 436yds and a Elk and Ibex again at 400yds. Someone documented a Cow Moose kill in AK with a 6.5Grendel and either a 18" or 20" barreled upper at 100yds as well with a one shot kill. The 6.5Grendel has a payload and ballistics to pretty much handle most Big Game as long as Shot Placement and Appropriate Distances are followed.
Its an incredibly great caliber for youth hunters, small framed beginner hunters, females, and others because its low recoiling, affordable to shoot alot and get very solid consistent hits with and build confidence with for the needed shot placements. In several states its not legal to hunt with a 5.56 but it is with a 6.5Grendel – CO for example requires a .240Cal or larger for Big Game Hunting and thus a 6.5Grendel is legal to hunt Big Game with, NM allows any center fired caliber but your limited in distance and size of game potentially with the 5.56 if you did hunt with it where as the 6.5Grendel can reasonably handle any Big Game animal in NM.

We have a YT Channel as well for hunting with ARs and a MeWe Group. Follow along or Join in and contribute pics and info if you are a Hunter using the AR platform

6.5 grendel can kiss my grendel.
Also, CMMG can kiss my grendel @ $1200+ for 4140 barrels.

WHAT? Waiting for it to cool down?? What is it made of wood? Your runnin a belt fed system..what are you talking about?

My 556 shots 2.2 miles…. I have no idea what the hell your talking about here…..

There musing 47 I need to re barrel in the 6.5 grandal still be able use AK47 mags 2 calibre rifle uppers

Cmmg is all cheap metals for high dollars

Grendel is better because you can use it to hunt deer and hogs. 1000 ft lbs at 300 yards is very adequate.

I could not make it more than 2 minutes into this video. Boring. I have used a .223 for deer and it is OK, but 100 grain bullets are the start point for a good deer rifle. There seems to be a mania for long range shooting these days with less than efficient cartridges. If you need "Specialty ammo" to get results, you are under gunned.

Do you think the CMMG 6.5 Grendel complete upper would work on my Daniel Defense DDM4 lower? And do you recommend getting a new BCG? New sub here and thanks for sharing.

This day and time the 6.5 is a fad that’s hard to feed.

The grendel is far superior to the 5.56! The military should have gone to the 6.5 grendel instead of the 6.8 spc! The man talking is full of bull! I have killed deer at 400 yards and dropped them dead in their tracks. The only drawback for a military rifle is that the ammo weighs about double the weight as the 5.56! A great designated marksman rifle. You can also use the ak 47. 7.63 x 39 cases to make cases for the 6.5 grendel!

bullet weight????

I don’t have the money for another rifle. I found a complete 6.5 Grendel upper for under 400. Do you think it’s worth the time to switch from 556 and 6.5 Grendel

Which is better? They are 2 very different platforms. Both have their uses . AR15 is a combat rifle workhorse if you will. The 6.5 Grendel at 20” is more of a DMR style rig . I have both and use 1 for 0-300 the other I use for 300-1500ish .

In COOPER COUNTY, MISSOURI deer have been taken with 6.5 grendel…at 250 yards in Big Muddy.

used to enjoy mine but the canadian meatsac of a PM decided to ignore the law and has tried to prohibit ARs

4:00 … who are frank and marc ? link ?

No, the Corps uses yards when we zero because our table 1 rifle qualification range is also in yards.
