Thanks Drax05Seasoning or Break in? The NRA and the National Shooting Sports Foundation have a procedure to break in modern rifle barrels, look it up. I used it to break in my Savage 10, 6.5 C, and my F class AR match bbl. There are some folks that have commented to me that modern rifle steel requires no break in. Well the Army Marksmanship Unit does it. Don't ever remember using a "set" procedure on my ML barrels, just shot, and shot, and.....cleaned and cleaned and.....Anyhow, I would imagine how well polished the ML barrel is to start with will have something to do with it also. I guess one can experiment on his own, can't hurt anything unless you "don't" clean it.
Good thinking, Winter HawkI was recently thinking about this very subject. If I clean the bores of my ML rifles with boiling hot water, they flash rust. The same for others who I have communicated with. The bores have supposedly been "seasoned". If they are, there should be NO rust. My cast iron frying pans which I use daily and often clean by filling with water and putting them on the stove to boil, NEVER flash rust. Once the water is boiling I scrape any crud that was on them off with a spatula, then scrub them out and finally rinse them clean. I've even been known to clean them with dish detergent (oh horrors!). They then go on the stove to heat up until all they are dry after which I grease the hot pans before putting them away. Again, NO flash rust. So obviously the barrels are not really seasoned, or the seasoning gets scrubbed out with regular cleaning.
