Would it be okay to clean my S&W 686 with the cleaning kit I got for my 9mm SIG P226? I think the bore brush should be basically the same size for both calibers right?

[Mal H]

Yep, that should be fine.

[Jim Watson]

Yes, but it is not big enough for the cylinder.
Get a .40 or even a .45 bronze brush and SCRUB those chambers.

[Mal H]

Do you really use a .45 caliber brush in .357 cylinders, Jim? Man, that's too much hard scrubbing for me.

[Lotzinger]

my gunsmith has special brushes for use in the cylinder - he tells everyone purchasing one NEVER to use it within the bore.

it must be made of something stronger than bronze and works very well (I shot a lot of wadcutter-stuff, so the cylinder needs heavy care).

see attachment !

Yeah I use a 40 in my 357 cylinders ......scrub the crap out of them too...:cool:

So, I need to just follow up a bit here, and make sure I have things clarified.

I understand that I can use the bore brush from my 9mm SIG P226 to clean the bore of my S&W 686.

But can I also use this to clean the cylinders of my S&W 686?

Also, is it ok to insert the bore brush from the tip of the barrel, if I use a bore brush guide? Thanks.

[45R]

Yes and Yes.

I use a 9mm or .357 borebrush for both the cylinder and bore.

I also push a brush down the barrel with a boreguide. Another option is a bore snake. These work great.
