+1 to what kraigwy said.
Except that I have used a coated cleaning rod since I got my rifle in 1981 without adverse effect. Several barrels later and it still likes the 4895 load.
jonnyc's post about primers is important . I have had slamfires as a result of what I later found to be bench rest primers. Primers known to be sensitive should be avoided. The rifle has few quirks. It just shoots.
The rifle is my absolute favorite. Lobing slugs into the X ring at 600 yards is something I hope I never get tired of.
