Super high quality brass, was very pleased with it. Came individually packaged in its own plastic ammo box with foam padding. Definitely worth buying!

Have not yet loaded these cases but they seem to be better quality than recent purchases from more well known brands. Very uniform lengths only varying a few thousandths with zero dings. Case mouth did need to be chamfered. Neck wall thickness was average from what I've seen from other brands, with a somewhat better variation of around 0.003". I like that they come in a very useful ammo box that can be used once loaded.

Only 4 stars because I haven't actually used this brass yet. But initial inspection looks good; measured headspace, necks, and lengths, and very uniform and within spec. Case walls are thick, so work up accordingly. Euro optic was impressive with their turnaround time. Ordered on Sunday night, and received my brass by Saturday afternoon. If all of the cases measure up like the random ones that I inspected, there will be no need to size these prior to loading.
