6.8 SPC

[Brandon.Hoagland]

Does anyone on here have any experience with the 6.8 SPC? I will be reloading for it in the near future. I have reloading data for it, but I am curious as to what others have been able to achieve out of their rifles

I shoot several AR's in 6.8 SPC. Currently a 12.5" and a 16". Both have ARP barrels. I settled on AA2200 as my go to powder for 90gr Speer Gold Dots and 95gr Barnes TTSX's. I have shot allot of coyotes and Rockchucks with my 12.5" since it's always banging around in a truck with me. I smoked a decent Muley ( Weak a_s fronts on his left side) with my 16". Shot was about 260 yards, got a complete pass through.

AR Performance barrels have always shot well. I have two in 6.8 SPC and a few others. 6.5x6.8 SPC, .224 Predator (.22 Grendel) .

110 accubond are also very good for deer--- if you get more advanced into loading for the cartridge then 130gr fusion bullets work great for longer range hunting and 130 vld for target but you have to load long and use unconventional powders.

The 90 gr gold dot and 95gr ttsx are great hog and white tail loads and the 90gr tnt are great target and varmint bullets

Very nice! What kind of velocities are you getting out of the 16" AR? I guess it's a more capable cartridge than what I thought! I was kinda skeptical and wondering if I should have gone with a different cartridge

We have a good friend that bought a 6.8 SPC II last year. He doesn't reload but told him I would help him out. He stopped by yesterday and he just bought a 300-BO so now have to ARs to work on.

There is a 6.8 forum. Lots of good load data. AA2200 is the most popular and fastest powder but it is temperature sensitive. Dont load max loads in cool weather and shoot in hot weather. The 123 gr sst is a good bullet as is the 100 gr accubond. +1 on ARP barrels. Use an adjustable gas block to tune the cycling.

Adjustable gas blocks were making me crazy! Constantly tuning them with different loads and with and without a suppressor attached. I went back to standard gas blocks. I picked up Bootleg adjustable bolt carrier groups and things got real simple, real quick.

They say they are supposed to be used for 5.56/.223. I have been using them in 6.8 SPC, 6mm ARC, 6x45 and .224 Predator. Without any issues.
