Needed some consistent reloads for IDPA & ran out of primers, with no time to buy more. Figured my WWB FMJ .40's would serve best as a source for cases & primers, so pulled 9 of them. While I was at it, weighed the powder charge. Don't know what kind of powder it was, but in the 9 shells, the weight range was 4.9 to 5.9 grains.. Not surprising, the average weight was 5.4 grains. Isn't that a large variation?
