Im looking for a scope to put on a Rem 700P .308 and can't decide which one. I won't be shooting past 500yds and I want a standard plex reticle. The two im considering are the Vortex Viper HS 4x16x44 and the Nikon M-308 4x16x42. Does anyone have any experience with these two scopes and if so how do they compare? Im also open to other suggestions and have a budget of about $500. Any and all feedback would be greatly appreciated. Thank You! Mike
