I have resisted shooting BP cartridges in my pre-smokeless revolvers because of the corrosion and cleanup problems, but now I'm getting nervous about harming the guns (and myself). I have looked everywhere on line for BP .32S&W but have been unable to locate any. Years ago I reloaded on a Dillon progressive but the only thing I have left is the case cleaner. Question: I have heard there are modern black powders that provide a non-corrosive charge and significantly reduce time and effort for cleanup. True? If so, I'll probably return to reloading. A side benefit would be I could reload light charges to allow me to fire that original Remington 1875 I have been wanting to buy.
