The round drops quite a bit after 200 yards. I was paying about $30 for a box of 20, the cost might be cheaper if you reload, I know there's a few guys here that reload for it, they'll be able to tell you more about that than I can. The recoil can be punishing on optics, I used to run a Trijicon red-dot sight that couldn't handle it, it was pretty frustrating. I had Magpul backup sights on it that handled it just fine, though, so maybe a good set of irons is a better bet.
Good equipment will never be a substitute for good training.
