Ok ill be the first to say it .300 Blackout is what you seek

okay...............(YAWN)

Yep.  Faster in a shorter barrel same weight... that's boring I guess.

The boring part might be the low bc bullet, since the OP wanted long range performance.

Do we still not know the OP's "range"?  Did I miss it?

Where did the OP go?  We have questions lol.

6.8SPC/.277 Wlv
100gr Accubond .323
110gr Accubond .370
Hornady 120gr SST .400
Hornady 110gr BTHP .360
Barnes 110gr TSX .323
Berger 130gr VLD .452
Berger 130gr CH .497

.223
Sierra 77gr OTM .372
Sierra 69gr OTM .301
Hornady 75gr OTM .395
Hornady 68gr OTM .355
Hornady 75gr Amax .435 (wont fit mags)

This 6.8/.277 BC thing gets so old.
It came about back when people were using the 85gr and 90gr bullets in the early days of the 6.8
The BC is not that different from a .223
It really is kind of a non factor until past 500 yards.
The 6.8 stays right there to 800 and 1000.
Past the legs of the .223 across the board.
Mark will have to comment on the Wlv range.

That said there is a guy at my local range that single loads 80gr and 90gr .223 loaded to 5.56 pressures and shoots 1000 yards with a 20in barrel.
Its his thing.
The OP just has to decide his.

I would personally consider .22 Beast, just to push the .224  bullets to the limits. Just think, if you can get 77gr bullets easily to 3000fps what might a 55 grain bullet do out of a 26" barrel!?

6mm Barnes 85TSX BC.333
6.8 Barnes 85TSX BC.246

Just sayn....

That is extremely important regarding this thread.  I'f we're talking 500-600 yards and nothing beyond that....the sub-22 caliber flyweights leaving the muzzle at 4,000fps are very hard to beat.

I know that is not the answer that any ARFCOMer wanted to hear.

Actually for the difference in bore you would have to compare it to the 110 TSX at .323
But really your confirming what I said.
Nobody on the 6.8 Forum talks much about that bullet anymore.
The focus not is not on the shorter bullets because now there are so many better bullets built specfically for the 6.8 and its speeds.
Before all the industry support folks had to use .270 varmint bullets, now there is 6.8 specfic bullets and newer powders.

The real long distance focus now is on the 130's
Xman has a 130gr running 2625, a 120SST @ 2740 and for hunting to 400yd a 100 Accubond @ 3075
Loading long with cut front mags and slower than usual powders.
But that not something I would recommend to the OP.

If you look @ Bretshooters post on this page you'll see why the 85tsx was mentioned.  Kinda of funny I should have to point that out since you were the original quotee...

Ahh.... with the Wolvie, yup you are correct on that point.
I was speaking of the 6.8
I should have had more coffee.....

Pay attention!    He was comparing the .277 Wolvies 85 TSX performance to the other calibers(6x45) 85 TSX performance.   Direct comparison.  Sir!

It's ok the BC comparisons are fair when you're talking long range, whatever long range might mean to the OP.  Which we're still missing. Under 500 yards the BC difference won't account for much considering you can push the 85TSX in the WLV to 2800 max, compared to the 2700 max in the 6x45 (correct me if I'm wrong), and out of a 16" barrel compared to a 20" barrel.

I don't argue with people... it's just math as I like to say.  If OP is talking 1,000 yards with no concern for energy then a lot of the other comments are correct.

This.
Thanks for the "Sir".
