[QUOTE="J E Custom, post: 1215416, member: 2736"] There have been many different methods tried that would/should improve barrel life. Chrome lined, QpQ, Nitride and others and even barrel material changes. the cost normally out weighs the improvement seen. the other issue with coatings is if they are hard enough to protect the bore, little if any machining can be done after the coating is applied. There are many things that can cause throat/bore erosion and no way to eliminate it yet (Maybe someday) typically a well made barrel that is uncoated will have the best accuracy, the coted/treated barrel will have the longer life. So one has to decide on accuracy or longevity. Chrome lined barrels are the most common, (Most military rifles are chrome lined for best ware under extreme conditions) but as we all know they are for the most part not as accurate as un lined barrels because they don't have to be and life is more important. It would be great if someone would come up with a process that could do both (Accuracy and longevity) Maybe one day. The only thing that I know of that can extend barrel life without sacrificing accuracy Is care. Hold that though thought (It would be nice) J E CUSTOM [/QUOTE]
