I currently shoot a IOR 3.5-18X50 and reallt like it. I live about 1.5 hrs from Camp Robinson Ark. I found a club that shoots up there once a month. 600yds one day and 1000yds the next. You don't have to shoot both days if you don't want to. I would like to go shoot the 600yd match, but I've heard most of these guys shoot very high magnifications 42X and higher. I have never tried to shoot this far and was wondering can I compete with my 18X? I have found a IOR Terminator 12-52X56 that I'm thinking about getting but don't know how this scope would be when I'm not shooting matches and I'm just out hog hunting or something. I don't want to get rid of the one I have if I don't need to, but I want to be able to compete also. Any input from guys that shoot these matches would be great and thanks in advance for your input.
