Hmm, you have killed 30 deer in your life time with 12ga slugs. I butcher about 25 deer a year that have been shot with 12ga's. You can compare it to a car (small rifle) and a Semi (slug). What does more damage when it hits it's target? Why do you not shoot large game with a small rifle. We are comparing apples to oranges! But, at the respected ranges, slugs out perform small caliper rifles i.e. .243 and depending on the ammo .270. You can go look at the ballistic charts yourself. Does your rifle leave exit wounds the size of your fist? And about you laughing. If you make a crappy shot with a slug vs a rifle. I bet you recover more deer with a slug shot deer. Like a said, big object, moving slow with a lot of energy at 50 yds, puts them down. It is hard for a deer to run away when you blow his leg clean off, just saying.
