A 30-30 definately packs enough punch to kill a turkey, or a horse for that matter. Better check your state game laws before you start firing away though. In alot of states, its illegal to hunt turkeys with a rifle. As far as mounting the bird, your taxidermist would probably appreciate you using your shotgun instead of the rifle.#6 shot holes are alot easier to repair than a .30 caliber rifle hole is going to be. Many taxidermists use artificial heads, others will freeze dry the head and repair the tiny holes. Anexperienced taxidermist is used to this type of job and they can work miracles.
