I need a minimum and maximum load range for a 185 gr. lead swaged SWC bullet over Unique powder. I usually use jacketed, but I am trying some lead rounds to save some money and have a few lbs. of Unique
Have you checked the Alliant website? I won't guess at their stated min & max, but years ago I shot a ton of 185gr lswc's over 5.0gr Unique, which gave about 675fps. Probably below Alliants recommended minimum, but with a 16# spring they functioned fine.
