i prefer to shoot at a stationary target...but then again who doesnt. it really depends on me tho...we have provate property and if a deer gets by one of us someone else will see it and get a shot. so i elect to pass most of the time if its more than a trot and i cant stop him. however after i touch one off...if he begins to run i will let two other slugs fly if i still believe i can male a good shot on him. last year shot at one three times...all three hits...2 in the kill zone...one a bit high but he was taken humainly as could be. thats just me..and im sure different ppl will answer differently depending on the way there hunting grounds are set up...population...private or public property...length of the season will all come into play
