I have a 30-338 win mag,wich in turn is a necked up 7mm mag or a necked down 338 mag.My delimma is i used 7mm necked up because i had 7mm brass,i have never turned the necks or length cut them and the brass is still to small,i can't neck fit them to my gun,or length them. /ubbthreads/images/graemlins/confused.gif
