So I got out as far as 80 yards today. It took some guesstimates and luck not to lose an arrow. After about 7 round I figured out that the top of my level bubble is exactly 80 yards (stupid luck). But concentratng on the top of the level had my left/right going all over the place. 100 yards is going to be interesting and i am going to need alot more practice and maybe a new sight
