Anybody Try IMR Enduron 4166?

I have a 100fps swing from 25 degrees to 50 degrees with RE15 in a mild 150gr 308 load. I may have to give some of this powder a try. Too bad I have 20lbs of RE15.

I've never been as enamored with Re15 as everyone else. It can shoot good, but it's a poor flowing powder with poor T stability. 8208 is a much easier to flow powder that has good T stability.

I have some 4166. 4166 is a good powder I suppose, but to me is a powder looking for a home. There's no sweet-spot for it. It's a coarse flowing powder with a burn rate in an overcrowded zone already, and is so bulky you can't get enough into cases where it should shine. I'm guessing maybe it's a good 30-06 powder, since that casing has lots of void space. But it's too fast for 6.5 CM, and too bulky for Grendel.
