Using it for the first time this morning on my M1 carbine, which I shot last Saturday and hadn't cleaned yet. I started at about 9:30 this morning and am still not finished. I realize the directions say that the first cleaning may be slow, but I haven't owned this gun long and its been shoot twice and this is the third cleaning, counting its initial break down and cleaning before shooting it the first time. When I cleaned it the last time I used break free, which I thought had gotten everything out of the barrel after the firs 50 rounds of Remington fmjs. Last week I tested some corbon dpx .30 carbine and federal jsp 30 carbine(it like the corbon, didn't like the federal one bit, more on that later), along with shooting my S&W M66 and M60. I cleaned the revovlers but didn't have time to do the carbine. Anyway, have been run a dampened patch through, then the brsuh and then dry patches, and repeating several times. Then running a wet patch through and letting it sit for 20 minutes, and repeating the forementioned process, a lot of black coming out of that barrel, amazing. Is this normal the first time to take so long to get it clean?
