Author Topic: Do you really have to switch cylinders? 475/480 -454/45 colt (Read 679 times)

Pardon my ignorance but if you can shoot 38's in a 357, and 44 specials in a 44 magnum. Why can't you shoot 480 rugers in 475 linebaugh with out changing cylinders? And what would happen if you did?

:? I was under the impression that you could. it is after all a short .475 Limbaugh. The marlin lever gun chambered for .475 was also able to accept the .480. Have also heard of other .475's that would shoot the .480. Just need to clean the cylinder holes thoroguhly like with the .38's in a .357.

From what I've read, BlkHawk73 is right. 480 Ruger can be fired from a 475 chamber, same with 45 Colt in a 454 chamber. I believe Freedom Arms sells separate cylinders for these calibers because they hold their chamber specs to a minimum. I think it voids the warranty (FA) if a person damages their gun by firing the shorter cartridges in longer chamber then switchs to the longer cartridge w/out adequate (or any) cleaning of the cylinder. I could be wrong though.

Thanks for the replies. That makes sense. I just can't imagine any one spending the money for a freedom Arms cylinder if they didn't need to. I am looking at getting a freedom arms and that is the reason for the question. Now I just have to decide between 454 or the 475.

SAAMI specs for the 454 Casull call for a very tight chamber and tight tolerances on the cartridge. On the other hand the SAAMI specs call for a very loose 45 Colt chamber and looser tolerances on the cartrdige. This is a hangover from black powder days when you had to leave room for the crud buildup. Once in a while you will find a 45 Colt cartridge that will not chamber in a 454 Casull. This is also why they recommend you use 454 dies for reloading the 454 and not 45 Colt dies. I have found that when loading cast bullets in 454 cases I will get a few that will not chamber. This due to cast bullets generally running .001 or so larger than jacketed bullets and that 454 chamber really is tight.
