I took the Knight Vision to the range today to try to get it sighted in, again. I seem to be having a fit with this rifle. I was excited at first with the 50 yard groups when I was adjusting the scope to put it in the bulls eye. But when I moved out to 100 yards the groups went to heck. I'm beginning to think it has something to do with Blackhorn 209. I have yet to find a load with that powder that any of my rifles likes. And at the cost of it, I'm thinking about giving up messing with Blackhorn 209.
