I have noticed a mark on the front of the crane that has come from the ejector rod shroud, it looks like it happened during firing as the mark dosn`t look like a scrape, on the shroud there's`s a shinny spot where contact was made. The cylinder still locks up good and tight no movement in yoke to frame.
Could this happen firing the heavy factory loads in the S&W500 or 460 or could it be a mark showing that someone down the line "cowboyed the cylinder shut" flipping the weight of the cylinder against the frame snapping it closed.
Reason why I ask is I am going to send the gun out for a camo job and am looking it all over for places that the camo may be damaged after it`s been applied I plan on polishing out the mark on the crane and removing the shinny mark on the shroud but will it return after firing the big kickers from the factory?
There`s a few X framers out there can you look at your guns and see if mine is an isolated problem or the normal passage into use.
Thanks.

After showing the revolver to three gunsmiths(none were sure) the opinion is that the mark came from closing the cylinder with forward pressure, meaning that when the cylinder was being closed the pressure was toward the muzzle and not to the frame.
This is a first for me I have been using revolvers since 1964 but this is my first X frame, polishing out the mark isn`t an issue also removing a touch at the bottom of the barrel shroud should keep it from happening again.

Interesting...with the new power found in the 460 and 500 cartridges there may be issues in the future because of the extreme pressures found with these rounds. However, S&W seems to have made a fine handgun to house these rounds. I`ve only taken a boar and whitetail with my XVR 460 and found that I need more range time to really know this powerful cartridge and handgun.
