Alpha Munitions 6mm ARC Brass

[BD1]

Something else I noticed after shooting the first 100 Alph Brass: The rims are thicker. My starline brass rims measure .050, while the Alph brass rims measure .055. About 1/3 of the fired brass have small burns from the extractor, both from chambering , and extracting. I polished the sharp corners and hopefully that will prevent the burrs
