    why would you want to neck down a 338 win mag to a 30 cal when all you got to do is buy 300 win mag brass. because thats what it would be.

    i guess it would make your neck longer if thats what you wanted to do.

    I do believe that 300 Win mag brass is longer than a 338 win Mag so that won't work.

    Are you trying to make 308 Norma Mag cases?

    See, the way I read it, he owns a 30-338 and some surplus 338 brass and wants to use the brass without buying a necking die? LB

    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

    Somebody correct me if I'm wrong, but isn't the 7mm win mag and the 300 win mag the same length case? If so that would explain why just neck sizing isn't working - the 338 win mag case is shorter - so a 7mm case is too long and won't fit in the chamber.

    .264WM, 7mmRem Mag, 338WM are all essentially the same case... all shorter than the 300WM.
