Im thinking about shooting some different sluggs from my 12 guage remington 870. Currently I use Copper solids and they are great but they are expensive and they are kind of hard to find anymore. Has anyone ever used hornady sst? Got a friend that swears by them but was wondering what you all may know about them. Also I want to get a better scope to put on my gun to I need a little more zoom what is an affordable scope for a shotgun? My gun is fully rifled as well. Any insight on these topics would be much appreciated
