I don't see any reason why a pump action wouldnt be as good as a bolt. The Model 14 pump is really built strong.
Long Hunter...I have read that the 30 Remington will handle hotter loads than the 30-30, also that the spiral magazine will handle soft point bullets. I just use the 30-30 data, When I first got my 30 Rem, I used 30-30 dies and just neck sized the brass. Even if you full length size them with 30-30, they will work just fine, but of course it is better to have the right dies. I havent heard of a Lee loader for 30 Remington, but they could be floating around out there somewhere. You could probably neck size them with any short 30 cal, even a 7.62x39 would work if you have the .308 expander ball.
