What a lucky young man and a great Dad. My opinion only but I like a little more trigger weight for young shooters say 3lb. but if he is doing well with it don't change a thing. Good choice on the 6x36 scope and I think those will be fine in super lows but ask Tally first. My boys did better with fixed power as they were always twisting the variables.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
