I practice out to a hundred yards. With a big bodied deer i would go 40yds probably. I have only lost one deer with a bow. A doe at 41yds.

That deer heard and was in motion reacting to the shot. She jumped back and i caught her across the front. Til that experience i honestly never had an appreciation for how fast they can react to noise.

The other deer i have killed were between 17 and 32yds.
