P-09 barrel, clean enough?

[Joe L]

Thanks, I have used the JB Bore paste on the .22, but very rarely on the 9mm.  I may give it a try. 

Here is the P-09 barrel after a few passes with a brush and Hoppe's, then a few patches.  I think all I really need to do is soak the barrel in solvent long enough to dissolve the carbon that is left. 

 

I might try a little JB Bore paste after I see if I can get the remaining carbon out with solvent alone.  Pretty sure the barrel is OK.  Keep in mind that the way I'm doing these photos exaggerates the dark deposits.

Yeah, Joe. Give it a try and let us know if does it help. I am curious if there is anything that helps this barrel.

I can understand a build up in the grooves, but with the jacket scraping down the lands every shot, how do you get a build up of powder residue/carbon on them?

[Vinny]

Before trying something abrasive, I think I would try M-Pro 7 as a penetrating residue cleaner; then an overnight barrel soak in Hoppe's. If it's copper fouling there's Hoppe's Elite Copper Terminator.

But I'm interested in learning what works; and the camera seems to tell the results.

What is Photo stacking?

What is Photo stacking?

The only way to get the length of the barrel in focus from chamber to muzzle is to take 50 photos with the focus point moved a few mm between shots and then merge all of the in-focus portions of each photo in to one finished "stacked" photo.  For these photos, I'm using a vise to hold the barrel and a tripod to hold the camera.  I'm using a camera that will automatically increment the focus distance so it takes less than 10 seconds to take 100 photos.  Then I copy the photos to my notebook computer, load them up in Helicon Focus 7 stacking program, cull out the bad shots, then hit "render" and the software does the rest.  Save the stack file as a .tiff, go in to DxO Photolab 3, crop slightly, increase the contrast, save as a .jpg, then upload the finished .jpg file to SmugMug, get a link to use on this forum, paste the link in to my smart a-- post. 

My P-09 barrel has been sitting in Hoppe's for 2 hours, I think I am going to go run some patches and see what else I can get out.

I bet there's a lot of extra clean guns these days, as well as better organized reloading areas, clean cars, pruned shrubs, about any chore that normally gets put off is getting done right by those stuck around the house.   

[Joe L]

So here is where I am after a couple of hours more in the Hoppe's.  Next is to let it soak for longer, then lots of brushing, then photograph the bore again.  Last thing to try is JB Bore paste.



It looks to me like it cleaned up a little more, but not as much as I was hoping.

Side by side, start on the left, current after cleaning right.

 

It is impossible to get the shot exactly at the same angle each time the barrel is removed from the vise. 

And here are two shots taken Friday morning after an overnight soak in Hoppe's Gun Cleaner (not #9) 10 strokes with a brush and 4 patches.

 

I think all I have done is documented what a lot of folks already knew--solvent takes some time and effort to get the carbon buildup to break up enough so that it can be removed.  I'm guilty of just not cleaning the bore often enough and letting it go too long without cleaning.  For a match gun.

Much better. Whatever left looks like erosion. So what was the whole procedure?

[Joe L]

Jurek--There may be a little erosion, won't know until I let it soak and do some more brushing/patching.  Please remember--the photos exaggerate the darker areas in the bore.  Whatever is left in the bore right now is very thin. 

Also, I don't think the accuracy was off in this barrel, even in its pre-clean condition.  I am pretty sure that, with a few rounds of remedial P-09 trigger control, I could shoot some good groups again with this pistol.  When I get the chance, I'll try it.  I've only needed to replace one pistol barrel, and that was a .22 Kadet, and it was only really eroded/rough in the chamber and leede area.

OK. I'm wondering if you find any better result after next soak/brush procedure.
Your pictures are perfect. BTW... remind me James Bond's opening sequence 

[Vinny]

Nice work Joe!
I've been thinking an overnight bath in an ounce of Hoppe's is worth a pound of elbow grease. 

I guess we'll see tomorrow.

[Joe L]

I added two Friday morning photos to the other 2 photos 4 posts up.

I am having some minor problems with my Lyman borescope so I can't provide good photos of the right angle view, but I was able to see enough to conclude that what is left in the bore now really is some very small pits.  These become exaggerated in the photos because of the shadow cast from the light at the end of the barrel.   Today, I will see if I can get some shots of the muzzle end of the barrel, maybe one land and groove at the very end.  I didn't see much of what I could call carbon when looking at the (poorly lit) Lyman borescope screen. 

I don't think the pitting is significant or will hurt the accuracy of the barrel.  I bet there has been some pitting develop since first shooting the gun.
