This sounds like an interesting idea for making a moderately hot 30cal without going full blown 300rum. Would you mind telling me a little more about these "stretch" cartridges?
If I read you correctly, you are lengthening standard WSMs slightly and increasing their case capacity...how much are you lengthening and how much more case capacity are you getting? And do you fireform from regular WSM brass?
I'm thinking that perhaps such a 30cal wildcat would produce enough down range punch to satisfy me, and still allow me to use a shorter/lighter action, compared to a RUM.
