Even at that range while you don't have to spend $500 there's an enormous difference between the NCStar/Millet/Whatever ChineseOpticsGuy $50-100 Trash VS stuff like Nikon, etc. I'll never own another bolt rifle with that trash on it again.
I once owned a Savage FP-10, it was a great rifle... completely ruined by the shit glass that someone had put on it. I think the original owner had a real scope but when he dumped the gun he put a millet or something on it so it would sell faster on consignment. I could tell it was swapped out because the anchors werent even tight on the damned thing and I must've wasted like $10 worth of 308 (in 2005 308 prices lol) just to zero the damned thing, only to find out the whole scope was moving because the prick didn't tighten it down.
I literally ended up selling the rifle because at the time I could not afford to re-glass it properly, and I wasn't going to have it collecting dust in my safe
in the interim... so I sent it down the river....
