Yeah, you won't find a Vortex for that kind of shooting in that range, but I don't do any kind of "serious" shooting like that. I've used their red-dots and cheaper ones like Strike Eagle and Crossfire, and they're more than fine for a few hundred yards. You can spend plenty on ones like the Viper and Golden Eagle. I've looked through them, but not at anything far away under high mag - they're a bit out of my league.
