A few months ago I bought Atlanta Arms 200 - 5.56x45 cartridges. 100 each of 55 gr Sierra BK and 100 of 77 gr. Sierra. I am inclined to buy a bunch more. The weights were very close and the case capacity was a bit better than the competition.

I weighed 20% of the box of 50 and the deprimed empty case weight only varied 0.8 grains from 94.2 to 95.0 grains. The fired case capacity was 31.2 grains, which will probably be about 30.6 when resized.



...

Have used Jagemann brass in several cartridges, both handgun and rifle, and it's always been very consistent in weight and dimensions.

From this little sampling, I can see why. I hope their being bought out doesn't affect quality. I will order more to play with. Jagemann brass isn't widely available up here.

I finished the volume samples. The FL resized cases hold 30.2 grains of water.
