When the " great powder crunch " came and Unique , among others became unavailable I switched to Winchester Super Field . I has not disappointed . In fact I don't look/ buy unique anymore . It's just a touch slower burn rate than unique , but only a little . It meters much better , was usually available and shoots very clean . I found load data a little thin so I started using unique load data to start . I find I'm adding about .5 of a grain more and sometimes a little less than that depending on the size / caliber of the cartridge in the final analysis .
In 38 , 5-5.3grs / 158 gr cast bullet , 44 spl -240 gr cast bullet I use 7.5 grs . I have read that in 9mm it is considered a " premier " powder . In the 357 mag --158 gr cast bullet gets 7.5 grs . 44 mag - 240 gr cast bullet gets 9.5 grs . In my S&W 25-5 ( 45 Colt ) -255 gr cast bullet I use 9.5 grs . I like it so much I buy 8#'s at a time . It gets a lot , I mean a lot of useage on my reloading table .
