Didn't know that T/C made a 300 RUM. Never seen or heard of one. Is it a T/C made barrel?
I have been around Encores for several years and never heard of a factory 300 RUM barrel either. If it is a RUM chambered barrel, my bet is that it has been rechambered or is an aftermarket barrel. Either way, the exploded barrel would not be a T/C problem/defect.
