I am researching a new target scope for 25 yard benchrest. At the moment I am using a Leupold fixed 36X which is excellent but am wondering about getting a variable from about 10X upwards as I may change rifles soon. The problem is getting a high magnification scope that will focus at 25 yards. I tried the big Hawke 10 - 50X but the highest that it will focus at 25 yards was only about 12X. Any suggestions for a suitable scope?
