    I did a search first but found nothing specific to the 6.8 SPC.
    My rifle is a Stag with 22.77 inch barrel.
    SSA brass, Hornady bras, Barnes 85, 95, grain bullets and SMK 115 OTM.
    I've been using primarily Rx10 based on advice from other forums.
    The 115 OTM act like they will produce 1" or better at 100 with some tweaking.
    I've been advised the 68 l"likes" the CCI 450 mag primer for better ballistics + accuracy and the CCI #41 primer also.
    I have and shoot the Speer 90 grain bullet with Rx7 and get close to an inch.
    I realize this isn't a long range target gun but more a light rifle for coyotes, other varmints and light deer, etc.
    I am however a bit anal about accuracy and like to squeeze all I can get out of any rifle I have.
    I think you all understand that.

    I do a lot of pig hunting with an AR in 6.8 with a 12.5" WOA barrel, 11 twist and SPCII chamber. Using the Barnes 85 TSX and 95 TTSX I get 1-1.5" groups @ 100. All loads are with SSA brass and AA2200. AA2200 is what many 6.8 reloaders are going to. The 68 seems to really like it, at least it the AR platform.

    These are my loads and *****MAY NOT BE SAFE IN YOUR RIFLE***** Work up to these because they are a little hot but no pressure signs in my rifle.
    Barnes 85gr TSX, 31gn AA2200, COL 2.285
    Barnes 95gr TTSX, 30gn AA2200, COL 2.295

    Hope this helps

    OK for an AR platform here are some loads to play with and as usual start at about 10% lower until you find your sweet spot.
    115 Grain SMK 29 grns. of H322 SSA brass 2.3 col and CCI #41

    120 grain Horn. SST 27.5 grns. of AA 2200, SSA brass & CCI# 41 col of 2.295 - 2.3"

    110 SPH 31.3 RL 10 X col 2.3 CCI # 41 & SSA brass col 2.3

    You should also try CCI400 and 450 SRM primers

    That should get you going and the AA 220 has become the powder of choice amongst most 6.8 shooters. I shoot both and LWRC & a Rem. LTR. in 6.8 with excellent results just remember this isn't a Long Range caliber so if you keep your sights on 200-275 yards. max you'll be fine in most cases!

    90gr Speer TNT, 29.5gr RL-7, Wolf SRM, SSA small primer brass has always worked well for me.
