Well I tried to load up .45 but I quit. Changed the 550 from .40 to .45, loaded some primers, set the powder measure to run a few test cases. Had a problem with primers not feeding, turns out I put the small primer bar back in so I got that fixed. Dumped bullets into the tray a spilled a few dozen on the floor and as I was getting up my arm hit the casing bin a dumped all 200 on the floor. After cleaning that up I am taking a break so I can get my focus back. Some times you need to take a break.
