Just wanted to see what everybody uses. I mostly use either an old single shot .22 or my .17hmr. However, went out with a friend on Saturday and took my old 20 gauge side by side. It is a European gun that was actually chambered for 2 1/2" shells but I got reamed out for 2 3/4". Not even sure of the make but man does it make it rain squirrels. Shot 4 in about 10 minutes and I think it may be my new favorite squirrel gun. So, what gun do you use and why?
