The granules of Select are all about the same size, and with no dust. Also when I switched from RS to Select my groups closed up substantially. With 100 grains of Select and a 430 grain maxie ball I was holding about 2 1/2" groups at 100 yards. At the time I was well pleased with that. It might even cure your flyers.
