Has anyone had any experience with them? I know Colion Noir was pimping them in IG lately, but for a local pickup their prices seem good.

9mm-$.20/500 rounds
.223-$.30/500 rounds

A couple of their sponsored shooters that's I've met have had great luck with their ammo.  That said, you can't beat the quality and prices from Freedom Munitions which have a store in Houston and of course ship online.  They are almost half the price.  I have been running Freedom's new 9mm 115RN and 124HP in 3 gun competitions for over 3 years now and their reman in practice sessions.  Runs 100% in my M&P Pro.

I've shot prob 20,000 rounds of stand 1 ammo. It's great stuff. Very accurate as well. I shot the 75 gr .223 match out to 1000 yards today.
 

IMO freedoms does not match Stand 1s quality.
