TX200 barrel cleaning
« on: February 08, 2019, 11:55:53 PM »
Seems like I'm having to clean this barrel very frequently to keep accuracy.  I've ran a brush through it and 50 full passes of jb bore paste and I still have to pull some patches through to regain my groups.  I'm not even making it to 100 shots.  I've tried a few different pellet lubes with the same results.  This happenes with JSB, AA and H&N pellets.

What can I do?  More passes with the bore paste?

You could try finishing up with a few passes of JB Bore Polish.

Brushing JB really does NOT do anything .... You need to use it on a FIRM / TIGHT fitting patch used on a round jag tip.  The JB needs to be forcefully burnished against the bore surface for it to actually have any surface smoothing properties.  That done and bore cleaned with solvent ... Running a few patches with TREWAX clear paste wax will further seal the surface porosity and decrease fouling.
* Slather a patch with wax and work it in back & forth ... leave it to dry in bore .... SHOOT it 30-40 shots to clear the wax & then run a few dry patches.  DONE !

TREWAX is used on hardwood floors etc ...

Been using on AG barrel bores for years ... It works !!!

Ed, you could try fire lapping.  That is, shooting perhaps 10 to 20 pellets rolled in JB compound.  The pellet creates high friction only on any part of the bore that is tight, rough, or "sticks up", while doing very little to nothing to sections that are depressed, or already loose.

Here is a less messy way to fire lap, that I used.  In a post below mine, another person states they use a variant of the process:  https://www.gatewaytoairguns.org/GTA/index.php?topic=150965.msg1543522#msg1543522
