In addition to casting slugs, I do a lot of trapshooting. When I started several years ago I used Red Dot and switched to 700X during the great powder shortage. I have cut back to 7/8 ounce and 15 grains of powder (approx. 1150 fps) due to getting old. 700X works well (functions my gas operated semi-auto), but is VERY dirty. I'd like to find something cleaner so I don't have to take the thing apart so often. Anyone have any info on IMR Red? Supposed to be pretty clean and works at a low pressure. Any help would be appreciated.
