Re: scope for 22 rifle to 300 yds that will focus 50 y
Tasco VAR62442M. Lists around $79.00.
42mm adjustable objective, focuses down to 15yd. Covered, resetable 1/4MOA Target knobs, 75+ MOA of elevation. 1" Tube.
6X-24X magnification, true Mil-Dot reticle, nominally ranges at 10x, some say 8x is more accurate. Some less than optimal brightness, but acceptable unless trying to use it around dawn or dusk.
To get optimal use of the elevation, I suggest using Burris Signature Zee rings, and using the offset inserts to build 20MOA of slope into the mounting. It may help with windage centering, too.
This is a genuinely surprising scope, performing and behaving much unlike its lowball pricetag would suggest. I have four, have had them in serious use since early 2006, including on my 1000yd Match rifle, and on my lightwieght .30-'06 M70 Hunter. I don't need more scopes right now, but that's what I'd get again if I did. The same model (mostly) is also made in 3.5-10x maganification.
