Re: new barrel break in / fire lapping
I never use to believe in any type of break in procedure. But lately, I've moved a little off dead center.
I just purchased a new 220 Swift barrel for my Encore. Now, when I got this delivered the bore was full of machine oil and "stuff" from the factory. So, I swabbed the bore with Butch's and a patch. (Did this with about 5 different patches) Then I ran a poly brush down it, and another Butch's soaked patch.
I was still getting a light brown patch. So, I bought some JB bore paste that comes with a small amount of oil. This is the non-EMBEDDING compound that is sold. I first ran an oil soaked patch down the barrel, then I applied the past. I ran the patch (patch is fairly tight in the bore....but not "knuckle busting" tight) down the bore for 20 strokes, then I cleaned the bore with Butch's, and again, ran a dry patch down the bore.
So, I got another clean patch, soaked it with Butch's and ran it down the bore. Well....this was the first one that came back with no...and I mean NO!!! dirt on it. There wasn't a hint of brown on this patch!!
So, I'm very pleased with JB. Now....I haven't had a chance to shoot this barrel yet, but maybe this weekend.
