Not sure why the 14.6 grain chart is still showing up below in this post after I deleted it so just ignore that one.
Much appreciated Safety Joe. Excuse my ignorance but can you please explain "Yellow Zone" and "Purple Zone" I'm thinking start and mid range loads? Bullseye is working real well. I have lots of pistol powders but the only other one I have been curious about is BE-86, which really doesn't have much data outside of Alliant's published data. Even that doesn't have much variance. I like it for 45 Colt but my go to 45 colt powder is 2400. I have a couple of pounds BE-86 in the cupboard and haven't touched it in awhile.
