Well unless the range is in a tropical zone and not likely being as it is only about 60 km. west of me you guy,s are going to have a tuff time seeing the targets at 100yds. being as we have a blizzard going on now. I have cabin fever so bad I almost went to Totem and started on new flooring in the bathroom. Think I will clean the muzzle loader instead. Cabin fever is a strange thing and when you get to this stage of it ( I hate both of theese jobs equally) you are very near the breaking point!!!!!
