FMJ vs LEAD

will FMJ bullets cause considerably more wear on the bore and forcing cone of revolvers (i.e. S&W models 686 & 64) vs. lead bullets?.
 
I have never heard that before, I've always considered copper plating to keep the lead fowling to a minimum for easier cleaning and since copper is not as dense and is still soft with an excellent transfer of heat I don't see how it would although I can't say that with any expertise to back it up.
 
In my opinion, you could say YES, it causes more wear, but I don't know if I'd go as far as to say "significant." It's been said that you couldn't wear out a revolver barrel shooting only lead (being sure to clean the lead out of course) but that you could with jacketed, but it would take a hell of a lot of shooting.

I wouldn't say it's something to really be concerned with. It is a good idea not to shoot jacketed ammo directly after shooting lead without scrubbing the lead from the bore-- "back in the day" they'd shoot some jacketed rounds to "clean the lead out" but these days, the word is that you'll simply be welding that lead in to the bore by sending jacketed rounds down after it.

has this been your experience?? how did you clean your gun afterwards??
 
i dont know from experience BUT i have read alot so in theroy yes it will thats why bronze rounds have a teflon coating aka "cop killers" bronze coated with teflon that is the teflon reduces wear u shouldnt have to worry about it with copper nearly as much unless u shoot thousands upon thousands of rounds often maybe in a 22 still if u shoot that much but for the most part only like todd jared and those pro shooters who are at the range every day have to worry about it
 
This has NOT been my experience, but that's simply because I don't do it, haven't tried it. I either shoot any lead after I shoot my jacketed, or more often, I typically stick to one or the other in each of my guns.

In most of my handguns, I'm slinging cast lead almost all of the time. Not 100%, and for the times I'm doing both, I simply shoot all my jacketed first and leave my lead for later.

Removing lead from a barrel can be done in a number of different ways, but when I've leaded up a barrel, I've mostly done it with a tight jag, a thick patch and a LOT of repetition and hard-ass work. Elbow grease. Not only is it a lot of work, but you learn QUICK not to do it again if you can help it.
