Years ago I wanted to go deer hunting. I owned one gun: Stevens 16 ga. SxS, bored IC&Mod. I got some Remington foster-style slugs and "sighted-in" at 40 yards. Left barrel shot 12"low and 12"right. Right barrel shot12" low and 12" left. Good enough for me; just need to allow a little Kentucky windage.

I never found out how it worked: didn't know much about deer hunting! On the other hand, I learned a lot about deer and what not to do when hunting them.
