[QUOTE="MagnumManiac, post: 316301, member: 10755"] I don't believe you can neck the others up/down to 7mmWSM due to the shoulder being further forward. You could neck down from 300WSM brass and leave an auxillary shoulder to headspace off, but that alone can cause problems. You would have to use a fireforming load, shotgun powder, cream 'o' wheat, and something to plug the case mouth like pumpkin or potato. This may eliminate the donut, but it may not also! I think it's too much trouble bothering with, IMHO. [/QUOTE]
