[QUOTE="azsugarbear, post: 1068690, member: 4809"] I guess I am not a quick as some to dismiss new ideas out of hand. There is no question the hBN protects against heat. It has been successfully used in industrial high temp processes for decades. In theory, coating the throat area in a new(er) barrel with hBN should help the throat area better resist the heat from overbore cartridges. The real question for me is whether or not the hBN can be successfully transferred from the bullet to the barrel/throat area before erosion begins to occur. If it can, then barrel/throat life should be extended. Time will tell. [/QUOTE]
