I shall try and trade you for your 6.8 upper, and if successful shall do several side by side comparisons to share with the group. I doubt that I will shoot any living creatures besides armidillos or coyotes.

Interesting....I wonder if the additional length of the case will limit bullet selection? Some of those 110gr bullets have a relatively lengthy ogive as compared to the 220gr. I'd be concerned they wouldn't seat well.

Also, additional expense of a 6.5 bolt....but if you already have a 6.5, that's negated. Either way, innovation is a rising tide for all boats. Cool, find..,thanks, lax!

Fuck that! More people need to get into the 300buttslut and help drive the price down! Feeding that thing is killing me.

It can probably be deep seated since you won't need as much case capacity for sub loads, since the smaller 300blk has enough case capacity to launch the big ones.

Right, I get that...what I'm more concerned with are supersonic loads and lighter bullets. With the case neck that much higher, I just wonder if it eliminates any bullets due to their ogive.

I am okay with 300 BO on my AR as the primary reason is to shoot suppressed which requires subs.

What about mag capacity seems like that one is a bit chunkier?

Again, though, a compromise.


It's a trade off. You don't get you use your 5.56 bolt or mags, but you aren't limited to the 300 BLK's shitty supersonic ballistics.

So you have to use a specific bolt, barrel, and mags? the only real benefit of this over .308 is using a standard AR-15 Lower?

6.5 uses different mags? I didn't know that....if that's true, it's another real con for non 6.5 owners already. One of the beautiful things about 300BLK is the bolt/mag compatibility.

but you aren't limited to the 300 BLK's shitty supersonic ballistics.
I think that's maybe a little unfair given the case dimensions but your point is vaild. It's not a super contender at distance.

I don't know about the mags, but yes to the barrel and bolt. NWS says you need different mags but I admit to being somewhat ignorant of the 6.5 AR platform.

The benefit of the round is that you get a more powerful .30 caliber round in an AR15 platform. Once you step it up to AR10, everything is bigger and heavier. So to get .30 performance in a lighter package is the goal...at least I assume.

Makes sense, I was just thinking that by the time you buy all the parts to shoot this round why wouldnt you be better off just getting a .308
