Well went out for some rangefinding today. Wearing very expensive varifocals and even though there were other problems, I really think my glasses absolutely destroyed my ability to see through the falcon T50 at higher mags. Result was, going home absolutely gutted thinking ive wasted a lot of money on gun and scope. I can only hope I get enough drive back to try again next week. If not my ar20ft and falcon are gonna go up for sale!
