If i were you i'd get the 20 gauge. Just as much accuracy and punching power as the 12 gauge with less recoil. I am regretting getting my deer tracker II in 12 gauge. Several of my friends and neighbors have the Ultra Slug Hunter in 20 gauge and absolutely love it.

I am also looking at getting a new slug gun setup. My son has an 870 20 ga. and loves it. I was thinking of getting the same thing, but wasn't sure if I wanted to go with the 20 or get a 12. With the newer slugs, it seems that the 12 has about the same range/accuracy as the 20's do.
What is anyones opinion?
