Oh, I forgot to add. The last couple of sessions with GOEX and PyrodexI was swabbing with straight 91% isopropyl alcohol with GREAT success, but hadn't tried it with T7. Well, that's all I used in this T7 session - one straight alcohol patch (both sides) between shots.Got the same results as with the other powders. Started with a pretty wet patch. By the time I swabbed, turned it over and swabbed again, and picked up the powder tube to load, the barrel wasdry and ready to load. That first side of the wet patch pulled out a lot of gunk and easily cut the slight crud ring I get with T7 in the Mustang.Even thattight fitting bullet/sabot combination loaded smoothly.
