Tonight was the first time I have ever weighed brass and I thought the results were a bit interesting. I am just getting into long range shooting so I thought it might be worthwhile to look into.
Recently I bought new 270 win Hornady brass and 30-06 norma brass. The Hornady brass had a 7 gr weight spread; with only 33 cases being within 3 gr that I will continue to use. The Norma brass had a 3 gr weight spread. This sounds normal.
For the heck of it I weighed some TAA 07 headstamped 5.56 brass that I had converted to 7.62x40wt; had a weight spread of 2 gr.
I know the 5.56 is a lot smaller case but I expected a large spread on the military cases.
