I'd check and/or calibrate your scale. jjron99 and I both used high end scales (he used a jewelers scale, I used a reloading scale), years apart.

1mo old box:
  • Avg Weight: 47.94grains 3.11grams
  • 95% +/- .7875grains .051grams

5mo old box:
  • Avg Weight: 48.03grains 3.11grams
  • 95% +/- 1.4321grains .09grams

I weighed and measured each round the same way. I used a reloading caliper and a jewelry scale for measurements. One interesting note is the box of "blue" field paint averaged .6840 with 10 rounds measuring at .6830

Based on my average results, I came to a very similar conclusion, close enough to concur with UV Halo's findings.
