Recently I had a 22 Hornet reamed into a K Hornet. Before reaming, the chamber had a radial runout of .0005". Post reaming the fire formed cases came out of the chamber with a .006" bulge just forward of the case web, in the same radial location each time. The bulge was such that the case would not rechamber unless it was indexed in the same position that it was shot. A number of fireformed cases were full length sized, reloaded, and fired resulting in the same condition. The gun smith's reply to my enquiry was, "That is part of the risk about going into an existing chamber". My question is, is this a reasonable risk to accept or did something go wrong that should not have been expected and is unacceptable?
