I seem to remember the plastic "cans" at Walmart say boxer primed for the Brass Maxx. I have been seeing reloadable Tulammo headstamp in range pickup lately.
Yep, boxer primed. I've reloaded it, I just throw them into my "Mixed brass" bucket and use them for plinking loads. Saw somewhere that it may be Fiocchi brass with a Tulammo headstamp, but I can't confirm that.
