These slugs are very good . As good as the Brenneke Rotwiel we used to get years ago . They shoot 4 inch 5 shot groups at 100 from my 14 inch 870 and my Benneli M4 and will shoot through a 300 pound bear at 26 paces and through a 10 point buck at 116 paces . I bought 4 boxes to try them and then bought 30 more boxes as i was down to my last 2 boxes of 3 inch Brenneke Rotweils and don't want to be caught short again .
