Long range slug guns...they are called muzzleloaders....

I had a Mossberg 500 here past few seasons.....IM DONE WITH THAT PILE...lol

It shoots ok at best and ive tried numerous different sabot rounds as well as scopes. Out past 75 yrds your throwing out a prayer withmy 500. I WAS going to get an H&R 12gauge here for the shotgun season, but opted out and bought myself a CVA Accura Stainless and mounted up the 2-7x32 Prostaff on it. Nice setup and best part is deadly accurate...
