A 12 guage shotgun? Do I remove it or what? Also, I got some slugs and lead bird shot for practice, but what should I get for actual hunting. I was told some slugs don't work well with smooth barrel shotguns. The slugs I got are for smooth bore barrel shotguns. My ammo is 2 3/4, but I can also shoot 3 inch from it also just fewer rounds in at one time. So for deer, what slug should I use? And if I do turkey what shells?
