Cool ,when they went to allowing optics I thought I might get back into it .
Turns out I got spoiled shooting F-class ,although I would still like to hit Camp Perry for the Pres 100.
Not sure about your eyesight but mine would start to wash out on the 600yd targets. I used the Bob Jones lense incert and it alowed me to get a better sight picture. I only used it for 600yds,2&300 were ok with out it .
