Red dot is/ was my replacement powder when the supply of bulls eye was short / non-existent. Used 3 grains in .38 loads and 4 grains for .45 acp. Both loads shot as well as the BE loads for 25 and 50 yard match stages.
Shooting 200 grain swc, either bayou bullets hitek coated or rim rock cast. Shot them in both a 1911 and 1955/45. Really no dirtier than the BE loads. The bayou coated bullets shoot MUCH cleaner than cast bullets with conventional lube.
