LOTS of info for the 6.8 SPC on AR platforms but not too much for bolt guns SO, I built one on a Savage short action. Turned out to be a real bug hole maker. Never ran it across a Chrony. They all go in the same hole so why bother? A 5 shot group at 100 yards, from the bench, that can be covered with a dime was/is good enough for me.
The only difference between the SPC and the SPC II is the throat length. Guys thought it better with the longer throat for hotter loads in the ARs? If you can't hit your target with the SPC, the SPC II won't be any better.
I went with the SPC over the II so I could shoot lighter bullets and stuff them into the shorter throat before the throat got too long. Shoot at 100 yards with no problem. A little hold over and you get to 400 yards with no problems.

I've been shooting 6.8 in mid range steel matches for about 5 years. I like the cartridge. A lot of guys like the 120sst over AA2200 for hunting. I have a 24" AR so I have to load a little differently than most, using slower powders. Good accuracy with H335 for me.

I have an AR but I couldn't see doing a re chamber job on it to the 6.8 SPC till I worked with that caliber a bit. Been a few years when I first saw the 6.8 brass. Happened to pick up a piece at the range. Had never seen one before and it looked interesting so I did a little research. Smaller than the .308/7.62 so less recoil. Larger than the .223/5.56 so a little more pep. Best of both worlds. Even joined the 6.8 SPC forum. Loads of AR loading info but next to nothing concerning the bolt gun platform.
Had to build one on a bolt gun. Ordered up a barrel from Pac Nor, brass and dies and started building loads. With the shorter SPC chamber, I can jam the bullets. The SPC II didn't impress me that much. Maybe at a later date but for now, I'll stick with what I have.
And it was said that there isn't much of a selection of bullets for the 6.8 SPC? Almost more to choose from than you can shoot in a lifetime. I started off with lite bullets and will go heavier as the throat wears and still be able to jam into the lands. Bug holes without too much work.
Was thinking about necking the SPC case down to 22 or even 20? Someone has probably already done it. We just can't leave things alone.

The only factory bolt guns that I read about were the Ruger. Pretty sure there's more out there. And it seems that you can get a Savage to feed the 6.8 by tweaking the mags a bit but don't know it for fact. And don't get caught up in something you don't want. Get it the way YOU WANT IT.

I have built 5-6 on ar platforms and getting moa isn't a problem with 120gr bullets. The best groups i got were with sierra 90gr varmenters, this target is the first time out with 90gr varmenters. I simply wanted to see how they would group so i didn't bother getting zero. I shot 9rds, 7 rds made the ragged hole. The two flyers are me not the round, this was at 100yds from the bench using a $30 mtm pistol rest and my shoulder. I don't have the load info here but should have it at storage with the left over 6.8 ammo. The dot is 1".

I've been getting good accracy using cnc turned copper match bullets over BLC2, consistent .6 MOA prone from a bipod and no rear bag. I have a custom throated chamber as I run heavy bullets seated long at matches that are slow fire/single feed only, I have a good load at magazine length with Hornady 110 bthp as well, that one is closer to .8 avg over hundred of rounds.
Most all barrels are now SPCII chambered, it came about as Remington made a mistake on the print submitted to SAAMI, never caught it, and SSA had some Tac ammo that was too hot for the shorter chamber, so it was revised to a longer throat and proper cone angle (army stated this was closer to their original chamber design than the SAAMI version). Bottom line, if you hand load, it doesn't matter. There isn't any TAC ammo on the market anymore and a lower pressure is a good thing anyways.

I currently have a Ruger Hawkeye and an 11.3” Wilson Combat. The SBR will out shoot the Ruger pretty easily and I can screw a can on the end.
I have had 16, 18, and 20 inch ARs in 6.8 spc/II and have used them to kill antelope, whitetail, mule deer, and coyotes. It kills much better than you would think given its case size and bullet selection. I wouldn’t feel bad using the round on elk at close range.
Remington made the 700 in 6.8 spc in a couple configurations.

Dk17hmr, what kind of accuracy are you getting out of your AR15s and what barrel length do you prefer if you don't mind me asking?
18" for a rifle is a my ideal length for most ARs. The 18" Black Hole barrel I had would consistently print 5/8" at 100. My 11.3" is a 1" gun but I haven't spent alot of time working on it yet.
I'm looking really hard at the Rock River X1. It has a 18" barrel. If it will shoot less than MOA I will be a happy camper.

I have one on an AR15 with a 20" barrel. I run the 110gr Hornady HP bullets. Never chronographed and only did minimal load development. Shooting 5 shots in 3/4" at 100 yards.
Havent shot an an animal with it, but I have shot water filled milk jugs. The 6.8 SPC makes a much more massive explosion than a 556
So there's definitely a lot more energy there

So there's definitely a lot more energy thereI have 16" 3/4 moa consistently, most of time better. It will kill, have killed 5 whitetail, 1 coyote, 2 deer shoot behind shoulder ran 40 yards or so 3 shoot neck, dry, baseball size exit. Definitely punches above its pay grade, you will be highly impressed, don't be afraid of shooting deer out to 250 or so. I shoot have shoot 100gr Acubond, and now shoot 85gr etip. By the way AR performance scout profile barrel AR, iwould suggest adjustible gas block.
You'll be happy with a RRA. Do a little snooping around at Wilson Combat's website. Bill Wilson shoots a 6.8 for all his hog hunting. I think he sells uppers too. One of my 16" barrels is one of his. Very happy with it.
I have 3...2-16's and an 18". Shoot Sierra, Nosler, and Barnes. Killed close to 200 hogs with them. Super fun rifle and caliber to shoot. Make sure you get a threaded barrel for a brake or can.
