This is a just a general question I had, because I read that importing steel core ammo was not legal...correct me if I am wrong. I have seen steel core, in 7.62x39, in some stores but it is expensive and corrosive. My question then is this, why not take the case, primer, and powder from a regular fmj round and make a non-jacketed steel bullet? You could get the proper dimensions of the steel bullet from the fmj bullet with the use of a micrometer, then you would just need to cut and polish it down to size. These seems cheaper to me than buying expensive and corrosive ammo. Would it be legal to do that? Does anyone do that?
