I only clean it when it tells me it needs it. About 200 rounds or so.
I'ts a Pac-nor stainless Super match with a really snug chamber.
I am only loading 89.5 gr. Retumbo for 2,750. Can go a little hotter but my E.S. is 4 fps! Thats for 15 shots.
All the Pac-nor barrels I've owned have lasted 2-3 times more shots than what others running different barrels got.
I don't over clean, I NEVER get them hot! 4 shots max! then cool it off. I use the slowest powder that I can use that gives me the lowest E.S. with acceptable velocity. Velocity won't make you a better shot, only RDR will do that. (rounds down range)...
And I Chryo all my barrels. Some say it's useless some don't. I've been doing it since they invented the idea. Easier cleaning, and accurate longer between cleanings.
I haven't used any treatment yet, but have read a bit on "Gun Juice" and will give it a try on my next barrel.
Whats the velocity with your Lapua and Berger?
Hey there,,,any idea how the Retumbo does with temp changes? H1000 is awesome regarding temps varations,,how's this poweder do??
