duckman,
I ran one on my long range dog rifle a 7mmRM. With my failing eyes I thought the glass was pretty decent. I would use the side focus constantly and then focus the hairs with the eye piece. For me 1/2 minute elevation was fast and accurate. Preferred over 1/4 minute for my application of the scope. If I were to use it as a primary all around hunting scope the cross hairs are IMO to thin & would be tough in low light. Personally the BDC stuff is useless at best being in the SFP which basically means you can only use it on 16x. And the spacing just isn't right for me. I'd prefer closer slashes for ranging and real fast hold over in the FFP.

I think the Viper HS LR was money well spent and if I ever do it again I would buy another. Hope that helps. But if you are an optics snob the best I can say is try one...you might like it.

Cheers,
Wild Bill
