My first electrical Boss was an ex-police officer... He saw three murders involving 20 gauges in particular, all were lethal and non were buckshot or slugs.. They were all well under 50' shot distance... Two of the occurences were indoors where the assailant didn't make it out of the house, and third didnt make it out the yard where he was shot... Non of this surprised me as I've hunted all my life and have seen volumes of examples of flesh versus different firearm cartridges... At 30-35 yard the damage becomes moderated on flesh --- 30 feet is different outcome... Wanna kill these ads? We can help!
