I am curious how hard it would be to rechamber a S&W N frame that is in 455 webley to 45 colt, I would like to take advantage of 45 colts lower chamber pressure and ease of getting brass, the chamber was already modified to accept the 45 colt rim but the chambers are still the length of 455 webley MKI so 45 acp length.
Is this something a guy coukd do them selfs or is this require a fair bit of skill and machines to do?
