I would do the paperclip test just to make sure there is not any incipient head separation. Most lever actions I would rather not know how they handle gas leakage. If it really is off then you could bump up in the 32 Win. die and then create a false shoulder. Not only are the chambers frequently on the big side but to compound the brass issue the dies are almost like small base dies from some manufacturers. The 30-30 is one I will shoot factory loads in as they are so cheap.
