I'm seeing this kinda late but here goes anyway. I'd not wanna trust some unknown brand of optic for a super accurate long range rifle like a .22-250 is at least supposed to be.
Mine isn't a Ruger (wow what a surprise to those that know me)

but rather a Remington M700 SPS Varmint. It wears a Bushnell Elite 4200 6-24 SF scope with mil dot reticle. I really can't think of a scope I'd rather have on it. I just wish I could afford another to replace the Elite 4200 6-24 AO that's on my SPS Varmint .223.
