A failure to plan is a plan for failure.
About the slug gun, I guess we have a definition problem of "in the woods". Where I've hunted "in the woods", the average visibility was, at the outside, 50 yards and often tighter than that.
At that distance, a rifled-barrel slug gun that one has taken the time to practice with, is going to give acceptable accuracy and, if you put it through the shoulder, the deer is going to drop right there.
If you hit a stalk of cane, a vine or shoot through elephant leaf, it's still going to hit the shoulder and the deer is still going down right there. You won't consistently get that result with a 223.
Now, if you are talking about *open* woods where you can see at some range, then, yeah, a 223 is far preferable to a slug gun.
OTOH, there are cartridges with excellent big game bullets available that would be preferable to the 223.
