Read a bunch about .45 Colt (appropriate) smokeless powers; I use 8 gr. Unique under a 250 gr. lead FN bullet. As most are aware, Unique is hard to get (at least at a reasonable price around here). Shoot the round in both an 1873 and USFA SAA - a perfect load for me. As I understand, Universal Clays duplicates Unique performance albeit with less soot. Is this a good route to go in the absence of Unique and does the Universal behave as stated - not sure if I can secure Universal either however if like performance, it at least gives me an alternative. Thanks.
