well there are different brenneke slugs out there foster's mostly and they also have sabots i've shot the rotweilers and ko's well they work very well on game they are hard hitting but like skane was saying not all guns like brenneke first time i tried them was in a ithaca 37 16ga and they jam on the ejection but in the rem 870 work fine the ko's so far have worked in ithaca's.My buddy only shoots brenneke's being rotweilers are no longer imported we had to switch him to HEAVY FIELD SHORT MAGNUM by brenneke he hasn't complained yet so my advice grab a box or to and try them
