Working pressure of a 30-30 is around 42'000 psi. A 360 Buchhammer is 50'000 psi.
A gun built for a 30-30 working pressure is a little weaker. I wouldn''t want to put my face behind the bolt of Steven 30-30 rechambered to 360 Buckhammer. Not much of a diffrence but might be enough for a few shots but when or if it does fail.

If someone did it would be a risk that they would assume. Not to mention I'm sure if someone was to do it they would do their homework. Not to mention put more than one or two rounds down range from a safe vantage point without having to be physically holding the rifle in their hands.

looking at this article on the 340 savage 30-30, it looks like the a bolt would need some work to allow the case head to feed up and under the extractor. I don't think I'd totally relie on the case mouth headspacing until the case snapped over a a Savage type extractor if it was crimped heavy.
