I agree with gunwizard, on the forming of the carbon ring in the cylinder when using the shorter brass. I always try to use brass designed for the cylinder……whether it be my .357’s, 44 Mags, or my 460 S&W…..I enjoy shooting light loads in all of them, much more than cleaning carbon rings! 😉 memtb
Only of you never clean your chambers. This is a non issue if you occasionally cleand the cylinders.
I do clean……occasionally! However, carbon is rather difficult to remove……much easier if it’s never been put there! Why risk carbon, when simply using a case of proper length for the cylinder will avoid this potential issue! memtb
I've fired a lot of 45 Colt cartridges in 454 and I have found it to be a problem
I read about it here on the net but I g ind it is over blown and not a concern of mine
Happy for you!
I bought a very lightly used 460 XVR, which had very few rounds through it….the majority of those being .454 Casull’s.
I aggressively cleaned it after purchase, though didn’t use a bore-scope to examine….as I have never had a carbon issue prior! When working on an accuracy load, I found that one chamber consistently through a shot outside of the group. I measured throats and found some slight differences. The cylinder was sent to a very reputable gunsmith to address the throats. One of his comments upon his work completion was a bit of carbon that required some pretty aggressive cleaning with a 50 cal brush and solvent.
The first thing I did at the time of purchase, was to buy a bunch of 460 brass…..I gave the .454 brass to a friend. “ALL” of my shooting was with 460 brass! Summary: with minimal shooting with short brass, there was a carbon deposit!
Should I have been more alert/aggressive with my initial cleaning …..yes! I never suspected that with minimal use it would have carbon deposits! Could the 50+ thousand psi chamber pressures from the .454’s be the cause for the very hard to remove carbon deposits……perhaps - maybe even likely!
Personally, I think that it’s not worth saving a few bucks to shoot short brass in my revolvers! JMO. memtb
