| Good read except,and this is not and opinion.There is no shotgun slug,even if it were steel would penertrate further than a 223. In fact if you take a piece of seel plate ,1/4 or 3/8 in and fire both at it you will see. I did a test and took a 7MM mag with 139 hornady aprox.3400 fps and a 22/250 53 gr serria hpat 3700 fps.on a piece of 3/8 steel plate. Only the 22 cut a hole. 180 gr sp in 06 put a big dent and that it |
