[QUOTE="Trickymissfit, post: 739921, member: 25383"] all sizing dies with one exception will not resize a mag case just above the belt. If you load them hot you will eventually have to get one of Larry Willis' dies. I had to get one for my 270 mag, and I'm nowhere as hot as I could be. Just the nature of the beast, and you learn to deal with it. The 257, 270, and 7mm WBY mags all use a lot of free bore, and the turbulance points are still inside the necks unlike the Winchester design. Their shoulder angle will figure out to be close to 45 degrees with a much longer neck length. A .257 mag necked upto 6.5 would probably have over double the throat life in a zero free bore throat. gary [/QUOTE]
