I don't see the problem.
Brass, resize 30-30 brass and reload with whatever 7mm bullets you want, in the contender you don't have to worry about having a flat nose.
Gatehouse has a thread somewhere here on reloading with pointed bullets for a 30-30 bolt action, he shortened the necks as well, I don't remember why. But you could do the same.
or you cold sell it to me real cheap.
