    Very nice. Impressive results for the range of weights in the little six eight. Good job. I'll have to try that powder.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Thanks for the report, I thought you were getting divorced from the 6.8 SPC ????

    I would sure appreciate if you do more research, if you could fire a "Control" group with Factory ammo. I don't reload anymore and would be curious what I am missing if anything. Thanks

    FP, I have a few lbs of 2200 here just waiting on my Worlds finest trimmer to come in so I can finish brass prep. Where are you getting your SSA brass from? I have 100 pieces that I ordered to my folks place down south and they forwarded up to me. All mine is unfired and I have been playing with the hornady stuff. I have boxes of both TTSX bullets you used as well as 85tsx, 90 sierra's, and some 110 pro-hunters. Just got a new chrony to replace the one I shot a couple weeks ago and a brand spanking new range membership so I am just about in business. I will try and work up to your loads with what bullets I have in my 16" ARP 11.25 twist 5R barrel.

    Interesting note on the dirty necks, I have seen the same thing on mine though it seems to lessen as the load gets hotter.

    Since nobody wanted to buy the 6.8 when it was a 16 inch carbine.... I did what any red-blooded Alaskan would do.. I threw money and time at it until it became a more expensive 24 inch rifle.

    I added a Black Hole Weaponry 24 inch barrel with 1 in 11 polygonal rifling, a full length gas system, a long 15 inch Aluminum free float hand-guard, and a couple other do-dads. The added velocity of the 24 inch barrel makes it viable for game critters and also gives it long range punch for varmint type critters.

    Edit:
    I bought 1,000 pieces of brass directly from Silver State Armory back when they went to small primers. I thought the 6.8mm would catch on and I was going to be the Alaskan brass source. As it turned out I have shot and reloaded it all a couple times.


    So far,,, AA-2200 has given me about 150-200 fps more velocity than other loads, but so far it is not as accurate as some other loads... Except for the 90 grain HP and 150 grain semi-spitzers. Which are about as accurate as you can ask for in an Ar platform.

    Float,

    Great info!! I have a 16" and a 20" so I think I'll try the 2200 in the longer barrel. I've come close to building a 6.5 upper a couple times but have settle on the 300 Blackout and 6.8 instead. I think they (and my 50 Beowulf) will do all that you need to do with the AR. I've shot the 110 Pro Hunter on fox to deer with excellent results and they will handle sheep, goat or caribou too...I believe.
    Somewhere along the way I have lost the ability to act politically correct. If you should find it, please feel free to keep it.

    I want to get some of the SSA factory 140 berger vld ammo. What I read on the 68 forums looks interesting.
    I can't help being a lazy, dumb, weekend warrior.......I have a JOB!
    I have less friends now!!

    If anyone here in the valley is looking for 2200 the Three Bears on Palm-Wa has it on the shelf. Arctic Ammo regularly orders it as well but it usually is gone before it hits the shelf.
