6.8 getting better

[no4njnk]

140 grain designed for longer range (500 pounds of energy at 800 yards), loaded with 450 magnum primers. I may have to try these out and see how they compare to my .308 at ranges less than 500 yards.

Still not that impressive. It also takes special mags plus a certain chamber.

my retriever caught one of those flyers at 500yrds and spit it back out at my feet.
i love that dog.

just get an ar-10

Yeah, I was all excited about a 6.8 upper for a lower until I actually did the research. Those numbers look really good though to me. I've just had too many people I know in real life/well that hate it. I'd be pissed if I spent 7-800 for a 6.8 upper and hated it. With 5.56/223 at least you know what you're getting.

The 6.8 isn't bad at a hunting round but I would never consider it a long range hunting round. As a general hunting bullet the 270 has one of the best SD's of bullets which causes better overall penetration but the velocity would be down too much for me to feel comfortable in being a long range hunting round.

Another note is this round uses Berger Bullets which are awesome target bullets but also can be very temperamental if they are seated out close to the lands.

6.8 Is probably one of the best compromise rounds available for an AR15. Every time you make a change you sacrifice something, there's no way to cheat. If you reload, 6.8spc makes a hell of a lot more sense. However, as someone who reloads I'd rather just own a .300 BLK because it's a hell of a lot cheaper even then. It's all relative. .300BLK actually has advantages over 6.8 at longer ranges in some circumstances.

I'm not huge in the realm of AR stuff but to me the 6.5 Grendel/264LBC offer the biggest bang for the buck if you're gonna do anything past the 300-400 yard range.

It's all relative. I shoot a .223 AR-15 1000 yards.

I understand that but being this original round (op) was designed more towards hunting at long ranges I think there are better options since a first round hit and well placed is imperative. The higher BC allows for better wind fighting ability the wind is your biggest enemy in this game the more you can cheat it the better off you are at achieving the pivotal shot placement.

No disagreement there. I believe a .300 has a better BC than a .270 doesn't it?

That totally depends on bullet weight. The more bullet weight per diameter, the better. I'm with dee on the 6.5's. A 140gn 6.5 bullet will have a better B/C than a .308, relative to it's velocity, until you step up to 200gn+ .308 bullets.

EDIT: It also bears mentioning, for anyone that may be interested, that sectional density plays a huge role in killing power, too. 6.5 has the 6.8 hands down in regard to both.

Say what you want about the 6.8 but it kills hog and dear within 300 yards better than anything I've ever used. Doesn't have much kick, uses most standard AR15 parts, and has a great amount of energy. I won't shoot much past 250-300 yards with it but I may play around with it. It's not the biggest or fastest but as mentioned its a great compromise of several rounds.

I like it better than the .300...since I already have it.

Not really sure since the .300 BLK primarily uses different bullets than your typical .308 caliber stuff. I believe that Sierra has come out with some 30 cal bullets specifically designed for the 300 since most will take up a lot of case capacity to fit within the spec oal length. Most 308 stuff has mediocre BC's when compared to some others one needs to get up past the 170gr stuff or push the 155's fast to really compete with the other offerings wind fighting ability.

Why did they hate it? I've owned two different 6.8 ARs and loved them both. I still own a 6.8 SBR. The updated chambers and full power loads from SSA make the rounds plenty impressive for me.

Well, it's boils down to reports from 2 people. Ones a local that I know is a great shot and another person I know. Both made claims of 6.8 not dropping boar at 100-200 yards, while their 308 guns have little to no problems.

The local to me person supposedly had this happen a few times.

Personally, I'm not out of the 6.8 race yet but leaning more towards a bolt 308 or AR10. I wanted to stay int he AR15 platform though..
