I think it is a good idea to practice shot placement on a look alike target. It's one thing to shoot at a target and another to shoot at a game animal. I forget where I bought them but several years ago I bought these cardboard deer targets for my grandson to pratice on. I really think it helped him prepare for the real thing by seeing something that looked like a deer when he looked down the sights and haveing to pick a spot on the deer in the kill zone rather than aim at a bullseye.
It must have worked because he is two bucks for two shots.
