It is good, in that leading of the barrel is greatly reduced. If your load is correct, and your cast bullets are good, it won't lead either. If you wanted to push the speed and load, the coating will help alleviate leading, however there are still limits to what you can do. If you wanted magnum loading you'd need either gas checked bullets or jacketed. Either way is a good option, just depends on what you want to accomplish. Lead bullets, light to medium loads, plastic coated medium to warm, jacket/gas check medium to heavy loads...
