I work around the corner from this range and go there once a month. When I was there a couple months ago, they had bags of 50 up to cans of 1000. As you go higher up in the 500 round range, they are very close to the gun show prices for reloads. Plus, they are local. I bought a bag of 50 and didn't have a problem with any of them.
I'm not affiliated with them in any way, just a patron. I do plan on going to the gun show on Black Friday just to compare.
