I 'practice' nearly every weekend. Usually we make it interesting and try all different conditions. One weekend it is just a grid target at 100 yds off a bench. The next, we go out to the public land around here and set up a safe area where we can shoot inmore realistic "hunting" conditions. We will set deer/elk targets up at varying distances and practice vital shots. Plus we do some "Bunny Bopping" and pick off jack rabbits in the west desert. (They are considered varmints here in Utah.) We shoot constantly!!

Reason

I have yet to loose a deer. always placed a perfect vital shot
I do this out of respect for the game I’m hunting. I hate it when I here of people giving up on tracking after a couple of hours, then they find the deer the next day, ravaged by yotes.
It's fun and I’m always tinkering with my loads to see what is optimal (right now 67Gr of RL 22 pushing a 140 gr sierra (target) or TSX (hunting)[/ol]
This is why I practice so much. And I thank you for being proficient, as you say, with your bow. I have seen way too many deer get tossed out because a crap shot bow hunter stuck him in the rear and the thing lived only to get infected and festered up!
