I have been stalking rabbits for some years with a .17hmr. So I am used to knowing the land, animal behavious, concealment, quiet movement, downwind approach and so on. Likewise shooting fairly small target out to about 100 yds and shooting prone, kneeling and occasionally standing. I am about to do DSC1, so have been successfully stalking the odd roe - but obviously without taking the shot - just for practice.
Clearly the backstop situation will be a bit different, as rabbits start off that much closer to the ground, and likewise everything after the shot is that much bigger.
But if you can stalk rabbits, is stalking deer that much different ?
