I've started loading E3 for my 9 minor, 124 Zeros, 3.6gr give 131PF out of my 5" 1911 SS. So far I really like it. It is a large flaked powder, reminds me of WST. It seems to meter pretty well, though the first throw might be a little heavy as it has time to settle between reloading sessions. I also like the large flakes, in that if somehow a case doesnt get a primer, the flakes are too large to dribble out the primer hole.
