i may be young and just a little bit stupid ok more then a little but me bein from mississippi myself i wouldnt recomend makeing a gun out of a rr spike mean i have poped a few of the holder ones with a hammer while the were cold and they broke in two. i wouldnt trust that with a giant slug comeing out one end and also the presure build up comein out the muzzle if it even makes it out the muzzle
