Then you would be out not only money but time as well!

I appreciate listening to other's experiences but sometimes mine don't match theirs. This is one of those times.

I don't have one custom gun. Some have slight modifications, such as sights or trigger jobs or chamfered cylinders or other minor polishing jobs, but every one I have had, with the exception of one 9mm, has taken lead bullets and shot well.

Work? Yes. To the gun? NO. It is much easier to change something with the bullet/powder/primer or whatever to make a gun shoot lead than have the gun changed. In my opinion, and that will get you nothing extra in most places, changing the firearm is not needed, neither are gas checks. I drive 12bhn to 18bhn bullets to over 1800fps on a regular basis without leading. Why would I want to add another step to my process? Because of someone else's experience? NOT!
