5 or 6 patches!? That barely gets the loose crud out at the beginning.
I clean every time I shoot, I know some dont. On average, I shoot 3-500 rounds of pistol a week, and probably about 1-500 rounds of rifle each month.
They all get cleaned right after getting home from the range, and they all get basically the same treatment. Certain precision rifles get a little more detail.
2 or 3 loose (on a slotted tip), wet patches to get the crud out, followed by a dry one just pushed through with the same tip. Beyond this, all patches are run though on a tight fitting jag. You need the jags if you want to get the patch to contact the barrel and get the crap out.
Then, alternating bronze and tornado type brushes with a dry patch in between, for roughly the same number of stokes as rounds fired split between the two.
Allow things to soak while attending to everything else, which all gets cleaned with wet patches of Hoppes, followed by a dry patch, then wet patches of Gun Scrubber until clean, the Eezox on everything.
After that, dry patches until the bore is dry, then clean the brushes with Gun Scrubber, and do the bore again a couple of stokes with each wet with Gun Scrubber, followed by a wet patch of the same.
The Gun Scrubber gets all the crud out of the brushes, when you run a wet brush with Gun Scrubber through, what comes out next, is whats left over, not something youre just putting back. I rarely get a dry patch after the brushing with Gun Scrubber to come out clean.
Depending on how dirty they are after the Gun Scrubber, I may start over, with the brush and solvent thing again, and do it all again. Doenst happen very often, but it does happen.
Once I do start to get fairly clean patches, I dry the bore and them run a couple of wet patches of Eezox down the bore and over the whole barrel. Wipe everything down dry, apply a very thin, light coat of TW25b to the barrel and rails and put it all back together.
5-6 patches? I usually go through one of the Southern Bloomer 1000 patch bags a month, and sometimes part of another.
If you really think your gun is clean, after your done and convinced it is, run a wet patch of Hoppes through the bore and let it sit for a couple of hours to overnight, then run a dry patch down the bore. I think you'll be surprised, if you already didnt know what was coming.
Precision rifles require more attention and care, and usually take more time.
For some reason, my Glocks (as well as the HK P7's I've owned) "polygonal" barrels are harder to clean than my other, traditional rifled barrels. The patches just keep coming out black long after the other guns are clean. I always thought it would have been the opposite.
As I said earlier, we all seem to have a different idea as to what clean is, and how to achieve it. And again, I've yet to find any real shortcuts. I've tried most all the "wonder" cleaners at some point, and at this point, use Hoppes, Shooters Choice, and Sweets (and occasionally some old GI bore cleaner because of ammo) for the bores, Hoppes, Gun Scrubber, and Eezox for everything.
