I have a couple of jugs of it myself I picked up in hopes of using it for both my .270 AM and my STW. I have only had a chance to basically test fire it to see that it went boom at this point as since it got here I have been too busy to really do any real load development. The stuff I have however is a bit faster than the AA-8700. I had the same idea as you, the 8700 looked good in several loads but we had enough to get some base line data from.
Hopefully soon things will settle down enough to get something downrange with it in several calibers. I will post up when I get something on it.
