I have one , it likes Lightfield 1-1/8 slugs ( 3 inch in red box ) . Most accurate slug gun i have owned . I plan to get the 20 ga. gun . They are a pain to load and 3 inch shells feed best . At 100 yards a 2 inch group or maybe less is doable on a windless day . That is if you can shoot a slug gun well ( no cut intended ) , check out the Tar hunt site on how to shoot one .
