That 541 is a beaut. Looked for one on and off over the years, but now the cost for one
is up where it should have always been for such a nice HB sporter.
Hey Danny, you seem to have a handle on your set ups, so I thought you
might share your process when seasoning the barrel to different brands of ammo when testing.

Thanks, JT.
As to seasoning barrels, it depends on the rifle and the ammo. For example, the Remington 541 takes about half a box to really settle in with an ammunition and more like a box when starting with a clean bore. Rifle smith Paul Voelker advised me to find an ammo it likes and "shoot it dirty." I seldom clean it's bore.
My eight CZ 452s? Five or ten rounds after changing to a different cartridge.
My CZ 513 Basic? None needed, an amazing idiosyncrasy of this rifle. Also, it never throws cold bore flyers.
My Anschutz? Five rounds.
By the way, if I'm changing from greasy/higher quality match ammo like Wolf or SK to a dryer cheap round like CCI Blazer or Aguila, I have found that the match-ammo-coated bore often carries over into higher performance for the cheap stuff for at least the first couple of groups.
I think really outrageous cold bore flyers are usually caused by a carbon fouling ring just ahead of the chamber. Scrub it the heck out of there with a quality brush, solvent, and bore-guided rod.
If I have a rough bore on an older rifle, I have had success with a fire lapping kit. Be careful though, this is like shock treatment. Use at your own risk and follow the directions to the letter. I have read of varying results and some smiths hate them. I suggest you only consider fire lapping when you can ask, "What have I got to lose?"
