Barrel Polishing Reason

[Bobbybeef]

I have a new 177 cal crown been having it a week have cleaned the barrel 3 or 4 times today i shot about 300 rounds the accuracy was definitely off by the end of the shooting session i was setting up the scope for FT next weekend the 1st 2nd & 3rd patch had ballistol on them and you could see flakes of lead in the patches. Would this be a good reason to polish the barrel?

I polished every barrel I own with JB Bore Bright before any shooting.

No regrets with several I have polished. If you search the archives here you will see the topic brings out strong opinions on both sides. Minimal downside if done carefully IMO.

my gun I think shot the same befor and after but I do think it helps get out all the burs or anything that might hang up a pellet , I did only start the rod from the breach end and ran it all the way out the muzzle , about 10 times so not to over do it and ran a few cleaning patches after to make shure it was all clean after

Yes, polishing the bore can significantly extend the time between which cleaning is necessary. It also makes the barrel easier to clean when the time comes.

If shooting pellets, you can also apply a hard wax to the clean bore and extend the time even further.

OK, some of you will consider me a few pellets short of a tin, but, I have something I'd like to share, and maybe even get some to thinking/doing. A trick I learned during my military career, from military gunsmiths, was/is to limit as much as possible,the use of grease and/or oil on...

First thing I do when accuracy isn't there is push a pellet down the barrel checking for tight/loose sections. If I find that I polish until it is diminished or eliminated. Last week I did the pellet check and found two tight spots in my barrel. One close to the breech and the other about 3" from the muzzle. I bore scoped the barrel and sure enough I had two bad rust spots building up. JB Polish removed the marks and the next pellet pushed through uniformly.

You can see where the lead was being shaved and adhering to the barrel. Normally I will have to do this about 3 times to get it all.

I finally got all the stuff I needed and the time to polish the barrel there is only 1 word to describe the results and it is WOW the accuracy is 10 times better shot first 22 shots after the polish and this is the results FX pellets 10.3 just grabbed out of the tin and not 1 flyer

I used 3 separate mops and JSB paste divided barrel into 3 and made 20 strokes in each quadrant and took the first mop when finished made 3 complete strokes end to end
