Re: Beartooth Bullets
Problem with firelapping is that it generally is most effective smoothing up the first 5 to 6" of the bore, not the entire barrel.
TO be honest I would do the following:
Get the heaviest 204 bullet you could get that was reasonably priced and load up a good medium to upper level load.
Clean the barrel to bare steel and shoot two rounds, clean the barrel totally again and repeat with another two rounds. I would do this until the muzzle did not foul with copper on two rounds and then I would switch to three rounds and cleaning, three rounds and clean.
Basically breaking the barrel in. I would do this until the rifle tells me it is smoothed up by the amount of fouling you are seeing at the muzzle.
If it does not smooth up after 50 rounds or so in this manor, I would seriously consider either contacting the factory for a replacement or better yet, save up for a custom pipe and have the rifle properly fitted with a new match grade barrel.
Some factory barrels chambered for rounds of this intensity simply do not polish up well.
One hint, after cleaning, get some high quality sulphur bases cutting oil and run a soaked patch back and forth in the bore for a few passes. Then take a dry patch and run it down the barrel pushing the excess oil out.
THis will leave a slight film of cutting oil on the steel and when you fire it it seems to help increase the smoothing action of the break in process.
