I live in rifle country as well but I hunted last year with my mossberg 835 slug gun. I didn't get anything, as usual.
Like you, I hunt in an area where shots are usually 50 yards or under, so laser accuracy isn't needed and a 12 ga slug pokes a really big hole.
I'm currently experimenting with hand loading my own slugs to cut costs a little. I've had some moderate success, but still have a few bugs to work out, especially with the sabots.
If anyone is interested, I've started to conduct some terminal performance testing of various slugs.

The 3.5" lightfields are just plain nasty!!
