[QUOTE="Shadowrider, post: 2452493, member: 3099"] The scuttlebutt I heard supposedly came from an Alliant rep. It was that e3 "has an identical burn rate to Red Dot but produces about 10% more energy". And the recommendation from Alliant was to use Red Dot, but if they insisted on using e3 start with Red Dot data and back off 10%. This was just them covering their butts because they have ZERO testing with e3 in metallic cartridges. There is a fairly extensive amount of data on Brian Enos' site for e3 and there are more than one who say it's just not as fast burning as the charts indicate. Some even say that it's possibly slower than N320. In most of the charts e3 is right up there with N310 and Red Dot. My impression is that e3 is indeed as fast as they say but is just very well behaved and not as "peaky" as most very fast powders. I say this because I get a very linear velocity curve from my chrono and can see the difference in just .1 grain increments. I've never been able to discern a difference by changing powder charges .1 grains and usually go .2 grains at a time for pistol. And I've taken e3 past where one could go with N310 or Clays and still had no pressure problems or velocity spikes. As I said before it is a fast powder, so be careful. [/QUOTE]
