[QUOTE="steve smith, post: 222223, member: 110"] It sounds like the chamber was cut a little big to me. Its simply to much pressure for a loose chamber. The main concern for the 45-70 case would be the thickness of the web in the case head. The thicker the web the more pressure it can handle. Case walls bulging is simply the amount of space that the case has to expand into. A tight chamber would allow you to run up to the max pressure the web can handle, before the brass starts to extrude into the little creavases in the bolt head, in the appropriate action of course.
