A few weeks ago I bought 20 pieces of Norma Brass from Midway. I was a little surprised at how much discrepancy there was in the weights, but all of the cases were around 92 or 93 grains. Last week, They had boxes of 50 .223 Norma ammo for sale for less than I paid for the 20 cases, so I bought 2 boxes. I went to the range yesterday and shot them all to fire form them to my chamber. Today when I began processing them I noticed that they felt heavier than the original 20, and indeed they all weighed in around 98 grains but still had quite a bit of discrepancy. Also, the headstamp was in a different "font". The original had a thicker engraved font that looked something like this norma .223 REM. The brass from the ammunition had a much finer font, more like this norma .223 REM. This headstamp is actually rather difficult to see.

Has anyone else noticed this? Is it just because it was produced in a different facility? or does Norma outsource some of its components?
