300blackout is my favorite but not as plentiful.

Then reload. .30 cal. bullets in a variety of weights are PLENTIFUL, and you can resize .223 or 5.56mm brass into .300 Blackout easily enough with the right tool. Primers are obviously small rifle.

I don't know what powders are best for .300 Blackout, I don't have an upper (or a dedicated rifle) for that yet. However, I've already started collecting brass when at the range - I have about 60 cases already, and every time I shoot I intend to look for more (and take them, if the shooter gives permission). Worst case scenario, I have extra brass that I could trade to someone for something that I need.

Then reload.

Good idea.....just curious, what is a reloading station going to cost and how much time is it going to take to learn how to load the rounds you're interested in?

With that being said, how about the powder and the brass and the various dies?

As far as I can tell,the best powder for the .300 is Accurate Arms 1680.I use it in 7.62x39-very consistent.
