What's up with AA2200 and QuickLoad?

[Hoot]

Forgive me if this has come up before. I'm working up a load to play with in my Remington Factory 30 RAR using AA2200. I looked at the Accurate Arms published load data for the 135gr Berger FB HP. I usually pick a modest starting point using QuickLoad and then ladder test up to the max looking for accuracy nodes. The two sources are drastically different. I know QL can some times be overly cautious because some morons go right to the max load but AA says a max load at 2.26 COL is 37.4gr of 2200. QL however, has a conniption fit over 35 gr, predicting that AA's published 37.4gr load of 54.6k psi is way up at 75.3k! Anyone else see this kind of disparity modeling AA2200 in QL for this or any other caliber? I'm guessing that in these litigious times, companies actually publish real world tested recipes and that QL has a problem either with the 30 RAR, AA2200 or both.

Thanks,

Hoot

Not much out there on Accurate 2200.

http://www.accuratepowder.com/wp-content/uploads/2011/04/DP2200.pdf

Information:
The original DP-2200 was a once off military surplus powder supplied for a limited time in the late
90’s. It’s an extremely fast burning powder. Only a few calibers were tested at the time which was
published on a small flyer/pamphlet.
Important note:
This product was re-introduced in 2010.
The older data still apply and new re-tested data will added in the future.
Please see our latest loadguide edition 3.5 on the load data page for newly tested data for calibers such as
the 223Remington, 6mmx45 and the 6.8SPC.
Special note on Semi auto Rifles:
Although it is quite suitable for use in the .223Remington/5.56mmx45NATO(There are thousands of people
using 2200 on standard AR15’s and M16’s without any problems), it might be that in some cases the
powder might be to fast burning for the combination. This is due to the fact that the duration (or timebase), of the pressure pulse is shorter than the more dedicated/optimized slower burning powders.
However, we periodically have complaints with specific weapons that experience functioning problems i.e.
short cycling.
