based upon reading another thread which talked about Trail Boss and the 45 auto load... I went to the mfg web site, got the formula and loaded some up last night. Used 230gr LRN and used mid-point powder load between their reco'd min and max amount of powder. Shot 50 of them at the range today with no issues. I don't remember the smell being so strong with my .38 Spl snow flake loads, but there is a distinct odor with the .45 In summary, they went bang, cycled the gun well, and were accurate for my purposes.
