Hello all - I'm looking for an inexpensive higher power scope for a .223 for longer range. I've noticed that Vortex generally gets good press and their Crossfire 6-24x50 in mil-dot has all the features I'm looking for. Does anyone have experience with this scope? I'm specifically wondering if anyone knows how well it tracks. Are there other scopes in this price range with these features I should consider? Any comments are appreciated.
