[QUOTE="Jinx-), post: 617938, member: 19791"] I was running some tests today, I cleaned carbon fouling and left copper alone, thing is in this particular barrel I don't see any copper, I guess last year I did proper "break-in" it was a mix of fire then clean with KG-1, KG-2, leave some KG-2 in the bore, just a trace, then fire again. So today I fired a string with my usual load and it took 4 shots before barrel stabilized, I mean first shot was 50 fps more then what I would get from faulted barrel, then the next had 10 fps decrees, so I fired 5 shots vertical string. The next 5 shots was within the range of the 5th shot I fired from the first group, 2nd group was OK group, 3 shots were duplicates and other 2 had +-5fps. This barrel was capable of shooting very tight groups, but today I couldn't make single one hole group. I could also blame my setup, like shooting from rocking folding table on uneven surface, then wind with updrafts and snow, but I would rather stick to the stabilizing barrel theory ;-) [/QUOTE]
