[QUOTE="emp1953, post: 2251031, member: 71817"] Not part of your problem but tupperware generates static electricity. Doesn't mix sell with 8lbs of powder. Next time pour 1 lb into your half full 8lber and roll it around, it will mix fine, Do it with all the 1lb containers. Modern day powder containers are designed to not generate static electricity. I'd say your brass is stretching, virgin brass will have slightly higher velocity than once or twice fired. You say your are full length sizing so that should bring tolerances down pretty close to new brass. Do you check case length before and after sizing and trim if necessary? Are you using the same manufacturers brass, maybe even from different lot numbers. New powders with the same burn rate h4350 for example should not change from lot to lot but they have been known to. That's why I try to buy a bunch of powder when I can from the same lot number. When you mixed up your powder you created a new lot number so to speak Not a bad practice by any means, I do it, but I keep in mind that when I chrony the subsequent loads that differences I see could be due to my new powder mix. That powder mixture will be your bench mark as far as performance data goes until your next powder purchase. [/QUOTE]
