Until 2019 I have used Swiss 1 1/2fg exclusively in my Sharps and Remington bpcr. When I ran short of Swiss that year I did some volume versus weight tests using my MVA powder thrower.By volume 78 gr of Swiss 1 1/2fg was the equivalent to 81 grains of WANO 2fg by weight in my test. The Wano shot well but is a bit dirtier. Curiously when filling the powder thrower with WANO dust came out the top which never happens with Swiss. I have used 3fg WANO in my .36 Seneca for years with excellent short range accuracy
