I for sure shoot better at about 15 than 20 , it's all in your form and if you work at it it will come,trouble is I don't work on it enough. Out of all the deer I have killed over the years I
haven't killed over 4 or 5 over 20 yards,I guess that's why I don't worry about it much.Most of my shots are less than 10 yards. 7 or 8 in what I try to set up for and with some patients you can get them kind of shots.
I have shot with guys that are very consistent at 20 to 40 yards but most shoot some sort of point of aim or style of gap shooting and are very concerned with arrows and draw weight staying the same or close,they also shoot the same bow most of the time. Me I shoot a lot of different bows and arrows, any where from 500 grain to 650 grain at 15 yards or less it don't make much difference,at 20 to 40 it dose.
It's like everything else in this,to each there own and how much work you want to put into you shooting. We talk about it all the time,we need to be shooting ,not scraping but it's hard for me to do that, so I settle for scraping and not being as good a shot as I probably could be with some effort.
