I have been thinking about trying it in 338lm and eventually 338edge imp. Plus it is dirt cheap, and you are right it is close to AA8700 in burn rate, but it is actually the discontinued original Hodgdons H870 that the millitary or homeland security pulled down from 50bmg tracer and 661grn tungsten rounds. I hear it is very accurate and consistant, but leaves your barrel looking like you've been burning coal. Hope that helps a little, WC857 is also a good one, its a ball version of H1000 btw. Good luck.
