Great for the price, few small issues
I ordered these and within two days they were shipped, arriving a few days later. The packaging was good and even included a free sticker (Bonus). The container had exactly 300 rounds, yes I counted. I noticed a few casings that were stamped as .223, which I hope isn't an issue stretching out the neck of previously fired .223 to accommodate .300 Blackout.
So far I've fired only about 90 rounds with no issues what-so-ever.
The reason I'm knocking off a star is that 7 of the casings in the container has dents in them. That concerns me a bit that it may weaken an already used round, so I'm tossing those out. I feel like quality control could be a bit better on that front.
All of that being said, I would order again.
