I went with the 20ga. after 25 years of hunting, I had enough of the 12ga. so 3 years ago I got it in 20ga. I have it topped off with a Leupold VX-II in 3-9x40, using Hornady SSTs. Let me say that this is a complete pleasure to shoot and is a track driver. Of course your gun may not like the SST slugs, so you might want to try a few differnt brands
