slug

If wearing body armor that could effectively stop a 12 Gauge Slug from penetrating, would the ridiculous momentum from the slug Knock the wearer over, if not send them flying back? A 1.25 Oz Slug @ 1551 FPS delivers 2920 Ft/Lbs of kinetic energy and 121 Ft/Lbs of momentum. What would happen?

Hey all I'm from WV where shots are almost always under 100 yards, I've been using a 30-06 with nosler ballistic tips and getting good results. My question is at this range are my bullets even expanding or using their potential or would I be better off with a 30-30 or slug shotgun?

I've read the Slug Groups and Pattern Spread (101) thread, and I've read the Box O' Truth #46, and I haven't seen this question specifically addressed. When shooting rifled slugs through a smoothbore barrel, is it safe to use any size choke? What size (or no choke at all) is typically best...
