Think you will find much better results with RL7, 2200 for 100g and above. RMR has the gold dots.

 

Accurate makes A2200, not Alliant.

 

Accurate A2200? Okie dokie! I'm digging again!

 

There are so many similar names it gets confusing.

 

2200 ~ 150fps faster than Reloader7

These velocities are from a 24" barrel and most likely Saami spec.
If you have an ARP barrel or other SpecII barrel you can probably load a little higher.
Work up carefully and watch for pressure signs

 

Try Hodgdon CFE BLK. It' given me the best velocity with 90 gr bullets yet.

 

If you are going to buy mail order (internet order) you will find that the HazMat fees are generally no different for one pound or eight.
Something to keep in mind.

 

@bugonpoint,
Yes sir. That caught my attention. If I can get 1 pound and it works like I want it too, I'm springing for the 8 lb canister. It only makes sense.

 

You might try hitting some local gun shows. None of the local shops, around me, carry AA2200 but I can usually find it at a local gun show.

 

I have 4 pounds of it if your close to Central FLorida.

 

Just order yourself an 8# keg from Powder Valley and just accept the fact that this is the go to powder for 6.8 spc and I am certain that you will load it all.
AA2200 is all I use to load for my 6.8s from AR-15 to bolt action.

 

Advantages of the AA2200 over the H CFE 223? Looking at the Speer load chart, the H is faster by a good bit. Different weights for different powders?
Gathering data for a just getting started newbe loader.

 

Cfe223 works with heavy bullets loaded long, but falls short in conventional loads. Cfeblk works well for 90gr loads, h322 is very consistent, and aa2200 is probably the best all around.

 

Bubba: FWIW, I've tried half a dozen powders with 6.8 bullets from 90 to 120 grains. I only found two powders that work well in this cartridge: Accurate 2200 and Hodgdon H322. Both are quite dense, something which is required in our little cases. A2200 is the best all around powder, ideal charges are approx. 29 grains for bullets 110 grains or less, 28 grains for 115 grain bullets and 27.5 grains for the 120s. H322 is very accurate, but with a little less energy/velocity. Most other powders in this burn range are not as dense and therefore you can't fit enough in the 6.8 SPC case. I suggest you buy a 1 lb can of each powder from Powder Valley, along with some Rem 7-1/2 primers and some bullets (100 grain Accubonds are excellent) and Hornady or Starline cases, and start experimenting. Always start a grain low on powder charges and work up until you get to optimum accuracy without swipes. BTW, the approx. $25 hazmat charge includes both packing and shipping cost. good luck - CW
