Uses? Caliber? Check out montana gold also, and they are FMJ
I've ordered and recieved my order quickly. They seem to be about the same as Berry's or Powerbond. Like mentioned above, the best would be to stop by Profire and buy them from Andrew if you are close. If not, order with confidence.
If your located anywhere near indy you can buy xtreme bullets at profire. I have ordered them online, but i can buy them for the same price from profire.
