A FMJ will come apart if it hits a hard enought resistance,and there are plenty of bones in a pigs shoulders. Most of the time a FMJ will ju;st pass throught if it doesn,t hit a bone,but hit one bone and it will bounce all over in the insides. Just a th;ought is it leagal to use a FMJ inf your state? Its not here. I love h;unting and shooting them. vangunsmith
