I was watching m1 carbine shows on YouTube and kept thinking that the 10 mm mag would be awesome in a m1 carbine .A pump 10 mm mag carbine that could shoot 40 sw 10 mm and 10 mm mag also crossed my mind .The 10 22 came from the m1 carbine and the 44 deer stalker also did somewhat. WE need some more good old guns tired of the new plastic ones coming out
