Agree wrt having good luck with "non-traditional" components. As we all know reloading to obtain military M1icon or M2 or Mx ball/AP performance using historical-type components is great stuff as is trying different things to tailor loads for accuracy, recoil, cost etc.. The experimentation is fun. The IMR Enduron powder line looks to offer good performance (at least 4166 does) with easy cleaning. Also performance over temperature is advertised as being more consistent.
I'm away from home for work this week but will post target this weekend.
