    My GP 100 is blued steel, and I shoot factory ammo through it (no where near 10,000 rds) maybe a few thousand but there isn't any indication around the cone like that. I load my .44 Rem Mags (out of a stainless 629 smith) and use IMR powder, again; nothing like what you're showing.

    Have you mic'd the projectiles? What is the .001" spread between boolets?

    @ Plinker no I haven't but all I've shot is full plated bullets I doubt it's lead I tried to brush it with a stainless steel brush scrape it with a flattened casing using it as a scraper nothing came off, it can't be lead. But I still can't believe it's the barrel steel, you imagine the temperature that it would take to melt I'm guessing hardened steel in the micro second it takes to push a bullet out of a barrel???
    My Redhawk is a Ruger though......and I still don't have a good explanation for why that's happening to yours.

    I haven't done that but I doubt it would have anything to do with the forcing cone surface. The powder (longshot) on the other hand might be the answer, it's the only other variable. Anyone knows what's the powder in a store bought round like Winchester?

    SS is actually soft stuff compared to carbon steel.
    "...powder in a store bought..." Manufacturers do not publish their load data. Reloaders can't get the powders the use anyway, but it's primarily because they load to get a particular velocity at a particular pressure with a specific powder lot. The powders they use may not be the same every time either.
