Since my favorite Rex-1 (and all Rex powders) are either no longer manufactured or no longer imported, I had to find a replacement. I used Rex because it was very cost effective, about $15 a lb. last purchased last spring. I debated about going back to Clays, but it's more expensive, and not any cleaner. Having made an inquiry here about a month or so ago, I was recommended Alliant e3. That's a powder I hadn't even heard of, not sure just how new it is. Alliant does have lots of loading data on their website. Locally was not available, so I stopped in at Graff's in Mexico, MO which I go past to see my back doctor in Columbia, MO. Got just 1 lb. at $15.16 retail.
I loaded 10 rounds at a time for chronographing, starting with a Mec #32 (17.0 gr.) bushing (which is 1 smaller than I had been using for Rex), With those results I dropped to a #30 (16.0 gr.) bushing which yielded pretty good results, but I went one more with a 29 bushing (15.5 gr.).
You can see by the chart the 29 bushing (15.5 gr.) went too light I have settled on the #30 bushing, (16.0 gr.).
This was shot using a 32" barrel in my BT99, so I imagine from a 28" barrel it will be down somewhere around 1100 fps. Guess I should chrono form my skeet gun next.
I will say it is very clean burning, one of the cleanest I have powders I have used.

Sorry about the chart, copy form Excel doesn't exactly transfer very well. Hope you can read it all right.
