[QUOTE="dok7mm, post: 1131284, member: 90080"] I have been looking at the HBN for a year or so and have been following this thread. I have gotten more solid information here than any of my own investigations. I am 95% sold on trying it in several rifles, but have a couple of questions that I have not seen addressed. 1. I have a good deal of IMR 7977 I am hoping to use and wonder if the CFE additive will have a negative impact on the bore coating process vs. non-CFE powders. Common sense tells me there would be even less fouling, but I wonder if the CFE agent might "erase" the HBN layer as well. 2. A couple of the subject rifles are unfired as of now and a couple have 2-250 rds fired (all are 26" 9 twist 5R Bartliens). I am wondering if I should start the new tubes with HBN during barrel break-in or after they settle in. The ALMOST NEW part caught my attention. Thanks to all for the very informative thread.
