Try Georgia Arms ammo as well. High quality stuff that I have used for 20 years or so ... including hunting ammo.
I'll have to look them up!
Damn! Never seen a 100 yard indoor range before!
The Wake County Firearms Center is a pretty awesome place. People bring the craziest weapons out to plink away at the 100 yard range.
The S&W 460 I posted above was a hand cannon, but bigger rifles are a common sight. I can't remember if it was a .308 Lapua or a .338 Lapua that a guy had out at the range time before last, but holy crap, what a boom!

I could have sworn it was yards, but oh well. It's a long ass range at any rate.
