[QUOTE="noel carlson, post: 287737, member: 16138"] AL, If you are competent at basic machine work (holding tolerances), there should be no fear of ruining a barrel. A true "bore-rider" will require a purpose specific chamber however, and recalibrated bourrelet dimensions to accomodate throat wear. The brass alloy which you will most likely come across is C-360. This has a very high zinc content (~35%), and does not act particularly well as a bearing material. It will tend to "plate-out" in the bore... but it is common, and inexpensive. If you move up to a bronze, or copper alloy, you will rapidly appreciate the material cost. Have fun. Best, Noel [/QUOTE]
