Yes, you may be pushing them too fast.
I shoot a lot of plated bullets in revolver. Mostly 38/44 Special. And a fair bit of 357 Mag too. But not 44 Magnum. (A lot of 45 ACP too, but that's not a revolver
.)
It's important to understand that plated bullets are meant to be a
cleaner alternative to lead bullets.
They were never meant to be a low cost substitute for jacketed bullets. Of course, as soon as they hit the market, loaders started treating them as such. I suppose the manufacturers should have seen that one coming.
I know the box says "1250 fps Max" or whatever, but I would never drive them that hard. With 38/44 Special, it's not much of an issue. I never go beyond 900-ish f/s - not as a rule, mind you, just that going beyond is outside my loading style/purpose. For 357 Mag, I go to about 1050-ish. If I want to go hotter, I cross over to jacketed.
Even at that, when I shoot a lot of plated bullets, there is an "orange hue" left behind in the barrel. I just clean as usual, and move on. If I still see a little orange after cleaning, I don't sweat it. It's never built up to the point where it's a problem. Been loading/shooting them for years.
I like plated bullets. But they have their rightful role. And being a substitute for jacketed bullets isn't it.
