Re: Scope for squirrels at 400 yards?
Whatever you choose, make sure it has fine duplex or better yet a dot reticle. I have a Bausch & Lomb Elite 4000 on my 222 Remington Mag, excellent glass and 1/8 click dial, perfect for long range shooting except the darn reticle is so thick for squirrel shooting. At 450 yards, the squirrel can hide in the reticle [img]/ubbthreads/images/graemlins/grin.gif[/img]. Cruise E-Bay and see if you can find an old 8X32 or the 6X24 Burris Signature or a 4X12 or 6X18 Vari-XII Leupold with fine duplex. They can be had for about the price of a Nikon Buckmaster or the Elite 3200. Excellent squirrel scopes IMO.
To achieve the maximum possible accuracy, all variables must be remove or at least minimize.
