magnum bore wear???

Now for a little history.......I read about the effects of lead and cylinder wear 30-35 years ago; don't remember the exact source of the information, it may have been an SAE paper, or some other source of automotive information. It was about cars, so I read it. The subject was interesting and unusual, and some of it just stuck in my head. Up to that point in time TEL was so posed to be good and we needed it for it's anti knock properties and as an exhaust valve seat lubricant. The article stated that there was a significant decrease in cylinder wear in Taxi cab and Police fleets in engines running on no-lead gas. Investigation discovered the lack of abrasive boride compounds formed during combustion (there is a lot of heat and pressure to break down molecular bonds and reform stuff). Since FI wasn't common place at the time I read the article, I'd say that FI isn't the major reason for lack of cylinder wear, logic says that you could still run leaded gas thru an injector and get cylinder wear. Though lead was/is a good lubricant, you shouldn't use it on your joy stick, Eythel is blonde, she doesn't know any better, too much lead causes nerological disorders and that is evident.
