As I learn this reloading obsession, I’m beginning to take in small observations while at the range. Since reloading I shoot a 10 1/2 inch 300 blk AR pistol and a 16 in .556 AR. I’m noticing “dust” on the table after shooting. As I learn, could this dust be unburned powder?
This observation has come while shooting 147 gr 300 blk with 14.8 gr of Winchester 296 (primers I’ll get to in a second) and/or from 55gr .223 with 22.5 gr of Winchester 748.
Since reading this and other reloading forums, I’ve seen most loading manuals indicate that small rifle magnum primers are recommended in the 300 blk loads. I’ve seems forums that say non-magnum small rifle primers can be used.
Has anyone else used non magnum small rifle primers and noticed any “dust”? My next load development will include 300 blk loaded with magnum & non magnum in an attempt to determine the source of the “dust”.
