J B and Kroil Cleaning Method

[Bottom Fodder]

I just use a cal. Sized bore mop soak in Koil and JB I’m sure there’s a reason your not supposed to

50 aint getting you too far if you notice how many goes on the jag.

Works real good just keep it clean

Great. Will give them a spin.

Just pay attention to the threads. I bought the VFG jag and pellets but didn’t realize I needed an 8-32 male to 8-36 male adapter to use w my rods.

I use IOSSO every 200-300 rounds. Kroil is what I have for oil but whatever you got to get the IOSSO out.. My regular procedure is Eliminator wet patch soak for 15 min followed with some brushing. Then I Kroil patch and repeat.

I do mine a little different because IMO, using solvent or oil with the JB or Iosso is messy and takes me more time. This is not my method. My gunsmith imparted the wisdom.

Like Dusty, I use a patch embedded with Iosso or JB with no oil added and short stroke my way down the barrel letting the patch advance a bit at a time with emphasis on the first 10 inches or so. Once I'm satisfied I've done the job, I pull the bore guide and clean it of all paste. I then re-insert the bore guide and run dry patches only through the bore. The dry patches pick up the paste better than a patch saturated with oil. I do this until the patches come out almost white, then it is a couple patches of a 50/50 mix of Kroil and Hoppes #9 and all done.

I used this process on my .257 Roberts. I used Carb Out first and then J B and Kroil followed by Sweets. The barrel was quite heavily fouled. The J B seemed to rough up the copper and strip away the surface so the Sweets could attack it. A lot of blue came out. I repeated the process, dry patching between chemicals, and could see some reduction in the blue. I finished it off by putting the barreled action muzzle down and poured Shooter's Choice in until it dripped out of the muzzle. Let it soak and then brushed with a nylon brush and dry patched it. The patches finally came out mostly clean. Do not have a bore scope so I will take it to the range and start shooting 3 shot groups. BTW, does Kroil prevent rust after all of this or do I need to use Clenzoil ?

Is it a stainless barrel? If its chrome moly i wouldnt put sweets in it

I used Kroil in the past and that's is where it will stay. Cannot figure out why anyone wants that gummy residue leaving product anywhere near firearms?

Sweets is fine on chrome moly - provided the directions are followed and all residue is removed quickly!
