What do you guys do when you get near the bottom of your powder jug? I noticed today that the stuff from bottom of the jug, not unlike the bottom of a cereal box, was a finer powder than the rest of the can. Basically 3f instead of 2f. When I opened the new can I was surprised to see what 2f 777 was supposed to look like. Do you just shoot it for fun? I have to believe that it's a hotter load. Any thoughts?
