This video perfectly laid out all of the information I was looking for and nothing that I wasn't on this topic. Thank you for the great work.

I watched the video you made on this exact subject later on and I see you’ve drastically changed your stance with the 6.5 Grendel 😂 The Grendel is an amazing cartridge, without a doubt my favorite caliber in an AR15

I think I had watched one too many videos saying how great the Grendel is in a suppressed sbr.

I really like your ammunition comparison videos. I find them super helpful

As NUTNFANCY would say, it's about the Purpose of Use. I just got into the 6.5 G about 4 months ago, but the 300 Blk about 3.5 years . Love them both, but I don't expect them to be the same for what I built then for. My 10.5 inch 300 is for Home Defense and short range hunting. The 16 inch 300 is good to go out to 150-200 yards, then I call it a day. My new 6.5G is an 18 inch SPR, and I look to go 800 yards with it. You called it right IMHO. I'd love to have a 12.5 inch 6.5, for the fun of it, as long as I have a CAN on it. I hate excessive muzzle blast. My 300 is for CQB, as in HD, and a 12.5 inch Grendel kills what the 6.5 G is all about; long range in an AR-15 package. Great Review!

I've been considering 6.5 grendel. I have a 300 blk with a 10.5" barrel and love it. The idea of just swapping out uppers is convenient. But with the prices today I'll have to wait.

Very Interesting. I have invested in the 300blk so ima have to stick with it. Rifle,loading dies, powder,primers,and the 30 cal bullet fits so many different pieces of brass. I have fun with it,and fill the freezer with food.

It'll certainly do the job. I keep talking like I'm going to do a 6.5 Grendel or 6mm ARC, but so far I'm still just 5.56 and 300 BLK for my AR's. They do the job well enough for everything I need. The other options may be cool, but I long since stopped spending money on cool.

I love how people comment that .300blk is only good for short barrel and suppressors. This is more then likely keyboard commando speculation. I run 125gr hollow points which I currently (6/21) get for about 95 cents a round. I hunt boar in Florida with this round and 1 shot drop them at up to 250 yards. So for someone to say its only use is for close quarters and for subsonic suppressed is fake news. I consistently take deer every year with Hornady black 110 Vmax and have killed them at 300 yards. This is all out of a 8" barrel. Again to say this round is only for close quarters or subs is just misinformation. Sure the 6.5 is better then .300 at greater distances... Look at the size of the dang cartridge lol. The .300blk was designed to give the M4 the ballistics of a AK with only a barrel change.

Thanks! I use 300blk for deer hunting 16" barrel 150 grn bullet works great. It's all 6 of 1 and 1/2 dozen of the other. I like the fact I can use the same bullet and load 30/30 , 300 black, 308 win ect ect... 30 cal is pretty useful in my world.

Sir. Great video. America fell in love with the 30-30. That's the simple Truth. It was capable of distance (250 yards) accurately previously unimaginable. US Generals from 1890 til 1960 thought it was Everything. Amusing. But true. 6.5X55 Swede was always better. And older. Not because it was larger or faster; because it didn't need to be. A better bullet of similar weight & velocity almost always wins. Especially past 300 yards.

6.5 is for range and 300 blk is for suppressed Close Quarters

I've got both. A 300 blk with an 8 inch barrel and a 6.5 with a 24 haha. This video made me happy about my choices.

Because they are both trying to bridge the gap between 5.56 and 7.62 at shorter ranges

The idea behind 300 blackout is good performance out of a short barrel AR. What does the 6.5 grendel do out of a 5.5 in barrel AR that can fit in a small bag or briefcase? How about a 8" barrel? Blackout is made for short barrels. For a 16" barrel AR, I went with 6.5 Creedmoor. 200fps better than 6.5 Grendel and no thin bolt face rim like the 6.5 Grendel.

well here it is 2022 and Grendel ammo is crazy priced and hard to find. the military turned it down and is thinking about the 6.8 spc but wants to change it a bit.

I've done an updated version of this video if you're interested. I revisit these kinda of topics as things change in the industry. Supply is definitely tough, but world wide adoption continues to increase. Yes, the US military isn't buying much these days, but to be fair, the 6.8 they are considering has nothing to do with any existing round at all other than bullet choices. Serbia, last I checked, is still adopting it as their standard round. Total sales and interest are higher than ever. Ammo for range fun is expensive. That's situational more than anything else. We'll have to wait and see. Actual hunting ammo, when you can find it, is actually on par or cheaper than a lot of the competition. I've seen more 6.5 Grendel hunting ammo in the past month than 30-06 or 6.5 Creedmoor. The real winner has been 308, which seems to finally be easily available in a wide variety. 223/5.56 as well, but for hunting purposes that's of marginal value. 300blk has been scarce locally but available online, but options are limited and prices high. Again, fairly situational. I think the lesson of this past couple years was simple, if you don't have it already when shit gets weird, you probably won't be able to easily get it so plan ahead. This is the same lesson as prior bans, panics and crisis. The whole few or many caliber argument just falls apart compared to just stacking it deep when you can.

@@BulletsNBrass personally i still don't understand why our government uses the very inaccurate 223/556. I've spent a good chunk of money trying to build a good range ar 15 in that and the ammo simply sucks if you can't hand load for that barrel. why you can take all most any length barrel in 6.5 and hit average groups of less the 1.5 and better if you try harder with no issue. heck my .22 lr is more accurate.

@BulletsNBrass

I've shot plenty of good 223, but never seen anything remotely decent that met the 5.56 standards. I agree that it is not a super accurate round by nature though. Most 223 and 5.56 is just not loaded for accuracy. Mil-Spec is certainly not particularly good in that regard. From a military perspective, they don't care. Individual soldiers might, but as an organization they don't consider the individual riflemen to be marksmen anymore. The Designated Marksmen (or scout snipers, or whatever other title their particular branch/unit uses) get different rifles and usually ammo that ARE much more accurate. The standard round was chosen for effectiveness at weight, size, and being effective ENOUGH at the required distances. They literally designed the rifle before they had the round. The AR15 and 223 came around because they scaled down the AR10 by request of the military and the first few options they considered for ammo didn't have enough energy. They created the 223/5.56 round to meet the requirements. It's essentially a 222 Remington on steroids. I honestly can't find any info on whether they ever actually designed an AR15 around the shorter round or even the earliest drawings had the current length max OAL. I'm sure it's out there, I just couldn't find it. What's funny is that the 222 Rem is actually a VERY accurate round, initially for varmint use and then it got very popular for a couple years in benchrest. I have a rifle my grandfather used to come in second at the nationals that is in 222 Rem and even today (after MANY more rounds than anyone expected that barrel to fire in its life span) it's still a slightly over bore diameter hole at 100 yards with any high quality ammo. It particularly likes the Superformance V-Max load but is still a ragged one hole group with the Fiocci.

Sadly true. My beloved (ok, maybe not that emotional) 300blk does not fair well if you don't prioritize the compatibility and sub sonics. Of course, we all know that the real answer is to get both. The 6.5 also suppresses pretty well if you don't try to go too short on the barrel too.

While none of this is new information for me I think you did a good job in the way that you presented it. I don't use the 300blk round or run a can. I do have rifles chambered for the 6.5. Your numbers and assessments are not to far off of my own. As the comment previous; each to its use case but I find the 6.5 far more versatile in almost any non suppressed use with non-SBR barrel lengths. Thanks for the content.

What is the best barrel length for the 6.5 Grendel in your opinion

@BulletsNBrass

Жыл бұрын

Really depends on your use case. As a short to medium range hunting rifle or personal defensive/shtf setup, 12-16. If you want to use the round’s ability to reach out there, you might want as long as 24”. For me, I would use it on an SBR at 12.5 or so, suppressed. That keeps my total length reasonable and I just accept the velocity loss. I also handload, so I would do loads that optimized for that rather than some theoretical barrel the manufacturers base their loads off of.

@BulletsNBrass

That's almost always going to come down to bullet choice. Bullets in the 6.5 that are meant for faster rounds may not expand properly. Plenty of match bullets aren't designed to expand at all, but people don't understand the differences and use them for hunting. Same with 300blk. You generally want it to go all the way through, what you don't want is for it to go right through and not have properly expanded. A skinny little hole with little tissue damage and "shock" for lack of a better term, does little to drop an animal. Shooting a bullet meant for a faster or slower round, despite being the same diameter, can cause it to either expand too rapidly and not penetrate well, or not expand at all. For hunting, if you don't need suppressed, there's little reason to do 300blk if you don't mind the extra initial hassle of getting different mags for 6.5 Grendel. I love 300blk, but when talking purely supersonic it's the inferior round in most circumstances. Price, availability... those can change that math, but for a pure hunting rifle that's a much smaller concern as long as the price an availability aren't totally impractical.

With super sonic ammo, you lose the concussive effect but still have a pretty substantial sonic crack. That'll be the same on both rounds. I still think it's worth it, and it's certainly a point in favor of 300 since you get full velocity without the longer barrel.

I can't easily look up prices from when I did the video, but currently, 70 cents a round for 6.5, 75 for 300, both are the russian import option so they're even similar quality. 6.5 will be more expensive to do a rifle, but the cheaper ammo is generally cheaper and will probably continue that way. Several countries are using it for their military now and general adoption is pretty good. 300 has excellent volume too, but is inherently more expensive ammo, particularly for the subsonics. That's just a quick look at SGAMMO, I haven't had my coffee yet, so I'm not shopping around and doing real research. They had it in stock and similar types so it worked. None of this necessarily means I haven't lost my bloody mind though, so you could be 100% right. lol Oh, and yes, I know I'm ignoring the fact that the AVERAGE price is higher for 6.5g, but in my experience there are two types of ammo. The type you shoot a bunch of and care about price, then the type you shoot very little of and are far more concerned with performance than price because compared to the competition or hunt the price is insignificant. GOOD 6.5 is definitely more expensive, but compared to other rounds used in situations where that matters, it's still competitive. Of course, that assumes you can find any right now. Damn shortages.
