Great point of view and summary from previous experience. Watching your 22 Nosler, 224 Val, and 6.5 Grendel videos my pick of the three is leaning towards 6.5 Grendel for the next upper. This video also gave me a lot to consider when deciding which cartridge to pick, other than 308, in a large frame AR. 260 Rem, 6.5 Creed, and 7mm-08 are in mind. More and more it seems like the mindset needs to be pick what bullet you want to shoot first and for what purpose then pick the cartridge best suited to shoot it.

[@J9_j3]

THE BEST cartridge comparison EVER!

[@DinoNucci]

It IS pretty legit

[@jonjames4281]

Spot on, 223/556 first... Now I understand what you were saying about the 22noz, and the 224v being different animals. thanks... the confusion over the 6.5g type 1 or 2 bolt face, along with the type 1 or 2 chamber/throat, (chaos), being all but over, seems like it's really a better choice. all that confusion didn't do the 6.5g any favors with peoples opinions. I like that I can buy cheap, bulk, Wolf ammo for the 6.5g for plinking while hand loading the good stuff for hunting and accuracy. not much different than the 223/556. excellent vid, thanks.

[@joshualance6005]

6.5 out performs 224 valkyrie in energy weight and bullet selection and ammo is cheaper 6.5 is better than 556 in every way possible

[@PatriotPaulUSA]

We should add an addendum of listing the awesome cartridges of .223, of course we have the .300 blkout and the awesome 22TCM! I recently learned of .22TCM while shopping reviews of the new Ruger 5.7. This awesome little pistol cartridge based on the .223 case cut and re-necked to .22 fires a 40 grain round out of a 17 shot 1911 at 2100+ FPS! Basically nearly the same as the 5.7! This smokes .22WMR by 250 FPS and 100 FtLbs! (it has roughly 400ft lbs of energy!) I have just found my next pistol that can be reloaded for cheap! There are rifles made for this amazing little caliber also. I will even get over my disdain for the poor politics of Illinois,Rock River Arms Co.who makes them. I see 1000 rounds .22TCM loaded are 149.95 or 200 rounds loaded sell for 31.99! Also we can reload it ourselves cheap! Lee and Hornady make dies! How did I miss this .22TCP ? I nearly bought a crappy trigger, expensive ammo, and hard to reload 5.7 cal Ruger. The 2 calibers handguns are about the same price, but the savings will continue forever with .223 based .22TCM! As a bonus the Rock River Arms 1911 handguns also come with a free 9mm barrel and a decent trigger that can be made like glass! Something FN and Ruger will never have with the 5.7.

[@darrinmcgann]

You've made up my mind. My next upper is gonna be 6.5 Grendel . Thanks

[@joshualance6005]

Can't beat the 6.5 grendel I love mine IV taken many white tail with it bullet selection is great and wolf ammo is only 230$ for 1000rds. Plus 1200yd range can't beat it

[@DinoNucci]

Oh dear, not another one

[@youreright7534]

I'm still shocked by how well 6.5 Grendel has held up over the years. Still the best ar15 platform round. 224 valk was supposed to dethrone it but it didn't, and same with 6mm arc. Performs great out of 12" barrels and does incredible with 16-20" barrels. Great for deer, hogs, coyote, etc. Has the best long range ballistics, and is in the top 3 for energy close range

[@itvnz]

This video has got everyone talking in the comments. I love the 223/556 and thrive on pushing it out down range. I also shoot 308 the same way. Have always been curious about the middle ground between 223/?/308. The Grendel seems to be that cartridge, and will be a build for me in the future. Thanks Johnny for your videos, it would take me way longer with more expense to get where I need to be.

[@joshualance6005]

Yes I love the 6.5 grendel IV taken many white tail with it it shoots 1200yds it's cheaper than the other cartridges wolf makes ammo 230$for 1000 mine gun shoots 11/2 in groups with it. and u can get really good bullet selection from 90grn to 147grain and higher and it has exelent barrel life

[@earnestarey3409]

Try blowing out the .223 case to a straight walled case to .355--.358 diameter bullet diameter that can be saboted back to use a .243 diameter bullet centered into the bore and check out the internal ballistics which will also gain a lot of external ballistics while still using near stock magazines. The stock formula is easy to find to predict how much better than the 30 caliber blackout

[@gregoblv5561]

Thank you for making this a separate video. I may not have watched one on the 22 Nosler or 224. They are not solid hits on my radar. I am working on a 223 Wylde, 300 Blackout and a 7.62x 39 builds and am really interested in the 6.5 Grendel, maybe next. And since I reload, your input on the brass issues really solidified my choices. Thanks again.

[@kirkboswell2575]

The 350 Legend is a purpose built cartridge to answer hunting regulations in certain regions. It does that very well. My personal issue with it is because it uses 355 diameter bullets while the common diameter for 35 caliber is 358. The cartridge is limited on bullet choice right out of the gate. Somebody wasn't thinking beyond the blueprints.

I found this fascinating and I don't even shoot rifles, and certainly don't re-load. Learnt a lot in this one video. One thing that perplexes me is that for YEARS I thought .223 and 5.56 were the exact same thing - just one expressed in inches (civilian) and the other metric (military). But recently I discovered that there are differences, like 5.56 slightly more powerful. Maybe Johnny has a video on this.

I have a .223 Wylde and a 7.62X39 AR. Neither are high end and just SHTF kind of toys. The AK in Drag is cool and like it. Mine are not free floated but are HBAR barrels. I still feel the best two cartridges for the AR15 are 223/5.56 and 6.5 Grendel.

[@joshualance6005]

Yep I like 6.5grendel it's the ultimate intermediate cartridge and is actually good for deer hunting so it's actually usefull

Good stuff as always. I enjoyed the comparison. I agree that is all depends on what you want to do. I think they all have their place in the lineup somewhere.

I also really like the 300 blk for the shorter barrel length that allows a much handier lighter and smaller rifle for an easy carrying option in the field and for hd.

Nosler and Federal missed the mark with the .22 Nosler and 22 Valkyrie. One of them should have looked to the 6mm ART40 or the 6mm FatRat and necked the Grendel case to .224 and 6mm. Hopefully Hornady or Lapua is smart enough to do it and get someone to start making mass produced AR barrels for it.

[@jamesl.5849]

When I deciding on new AR-15 round, I looked at average customer reviews of ammo on MidwayUSA. With the idea comparing cartridges for customer satisfaction. People in general are happy with 223 Rem(4.66/5.0), 22 Nosler(4.68/5.0), and 6.5 Grendel(4.66/5.0). But factory 224 Valkyrie Ammo in 224 Valkyrie Rifles are generally a poor performer(3.86/5.0). I decide months back to buy a Grendel upper over 224 Valkyrie, back then the factory ammo was about 3.5/5.0 since then, quality of ammo is starting to improving now 3.86/5.0.

I would like to see a head to head competition with 22 Nosler and 224 Valkyrie using same bullet and same powder. Something with bullet and powder that shot well out of both guns. Thinking IMR 4451 and a bullet suited to both calibers like the 85 RDF, 88 Hornady, etc. I’m just curious if the performance is much different when you get into those bigger pills.

I wish the Grendel had a smaller case head like the Valkyrie but then it might suffer from the same issues as the Valkyrie. If I were going to a heavier bullet the Grendel would be my choice over the Blackout for shooting longer ranges here in the West.

[@colsoncustoms8994]

Have you ever messed with the 69 grain Sierra TMK bullets? I've never tried them in my .223, but they fly really nice out of my .22-250 bolt gun. Right around 3100 fps with single digit SD's. I could probably push them a bit faster, but my current load is super accurate. Sierra will never suggest their TMK bullets for hunting, but I've found they are amazing performers on White Tailed Deer.

[@longobardir]

Grendel has 3000psi less pressure per SAAMI 52k vs 55k than the other rounds, maybe why it is easier on the brass. I had some handloads exceed 2800 with 130gr MK's and those were wayy overgassed and scarred the brass on the extractor and deflector. ( i do like those tho, primers are just barely flattening and my 1000yd traj. is sweet). I load for .223, .300aac and many more too, don't have a .22 nosler or Valk though. I was just too invested in grendel when they came out and most ballistic calcs led me to the same conclusion, Grendel is about the best all around in the standard ar15 platform.

[@michaelw.urbansr.8617]

Yano i have always purchased Faxon for barrels or in a pintch ill hit Ballistic Advantage? But i am just getting into long range shooting and thinking about competitions? I live in a very flat open state so i need range that can still humainly do the job at distance. So for both my 224Val and 6.5Gren i have 20" barrels on. I also have a 5.56 with a 20" as well as a few with 16: barrels in 5.56 as i love the M4 fixed front sight post carbines! I only have a couple of fixed M4's and both shoot great! one is a run of the mill Del-Ton sport gen2 and the other a bit higher up the food chain yet not crazy expensive a Stag Minimalist. Both shoot just as well as my all Aero Precision i finally built my self although it is a free floated barrel. All of my other AR's no matter the caliber are 16" carbines ,sadly. Although i just purchased a complete Lr/AR-10 upper and have just got all the parts in for the lower and its all on my storage cabinet! I have decided to clear out my work table in the garage and plan to finish it up and put it together next weekend? It's a .308 with a 20" barrel only because, I couldnt find a longer one any where else? LOL I would like a 24" barrel with a 17" forend! lthough when we get into these lengths the pressure put on the hand guards whether its a bi-pod or a stump in the field will effect your shooting. Personally i have found if i want to take a deer or elk i will go to my bolt guns. If its hogs or medium to smaller game the ARs are just fine. I have a nice 350Legend and a 458Socom if i need to take out a bear or larger hogs. the 224Val and 6.5Gren work best for me here.

If you need a better round for big game hunting and distant shooting then upgrade to an ar10 that shoots 30cal "by design". The ar 15 was designed to shoot low kinetic energy projectiles at a short range with extreme accuracy. The ar10 shoots a high kinetic energy projectile at long range with great accuracy. Creating these Frankenstein guns only puts unnecessary wear and tear on the frame of the platform. Unless you competition shoot (were you are constantly breaking the gun down and fine tuning it with expensive replacement parts) then its not worth it. Having a badass Frankenstein fun doesnt make you a badass shooter.

Great channel - I've also watched most of 224 Valk videos. I use CCI #41 primers and found primer pocket enlargement problems in 224 V and 6.5 Grendel near max loads. If I back them down I still get max velocities with lower charges. I think it's the nature of the "magnum" primer. I use QL and adjust the burn factor until the velocity matches my LabRadar - and if that velocity shown is not over max pressure - primer pocket failures seem to subside. It's close. I usually go down .2 or .3 less to accommodate warmer temps. I also noticed this issue with #34 CCI in 6.5 Creedmoor. Just my 2 cents and theory. I use a pocket primer Gage to check.

Thanx for the vid. You sound almost like Nicolas Cage ....

Not to mention, until Biden made Russian ammo illegal, the 6.5 Grendel Wolf ammo was super reliable and accurate out of most AR'S!!! Was lucky enough to buy a few cases of it and overly impressed with the steel cased Wolf 6.5 Grendel cartridge!!

What about the.243 Winchester. I know it’s not a AR - but you can get a 308 in the AR style rifle. Maybe you should get a AR 10 chambered in .243

ElNino BigDog i think hes got a 6.5 Creedmoor AR-10

[@elninobigdog7211]

Yeah I think he does but what about a AR in 243 cal
