It's been said the pulling a bronze brush back through the bore will take away the sharpness of a crown. Can someone attest to this from experience? I want to get Dave Masons crown repair tool but Sheeeeze... $$360.00??!!
 
If your brushing your bores I would look into nylon. I'm not a fan of brushing bores. I would rather use patches and a jag and just use a ton of patches. Just my opinion on it but it does work well and only treats the fouling if done correctly. Scotty
 
Bullets, swabs, patches, solvent. Nothing else goes down any of my barrells.
 
I use a nylon brush every now and then.

I would sure think that a smith would recrown the barrel for a hell of a lot less tha $360 :shock: That seems very steep!

Yeah a little steep.... be nice though to dress up crowns from time to time and not have to wait an eternity for service from a smith.
 
I use brushes. Bronze is softer then steel, way softer. I even use the Hoppies stainless whirlie brushed, but again they are way softer then the barrel steel. I've never had an issue.

However, I have had several occasion where I had to fix rifles for guys who only used patches and second rate copper solvents. It's amazing what you can get out of a barrel with a tornado brush and some CR-10.

I use a mixtue of Shooters Choice and Kroil.... what's considered second rate?
 
I use the brushes on my handguns and shotguns, not so much in rifles just because i usually clean them ever 20-40 shots whereas with the pistols and shotguns, it can be more like every 60-100 rounds. I do have some of those Boresnakes I use if I am in a hurry and they have a brush in them. But I have never seen any kind of erosion in the crown from them. I would hope my barrel steel is stronger than that.

360.00 for a recrown seems outrageous. I had a gunny rebarrel a M98 to 30-06 for my Grandfather a couple months back for less than that! You could nearly buy a new rifle with that kind of money.

Hoppes, dry patches, Cr-10, wait 8 min, dry patches, Hoppes and then more dry patches, light oiled patches and one more dry patch... that is my mode of cleaning.
 
Brownells sells a crown polishing tool which is used in an elec drill with fine lapping cmpd. Probably not as good as the barrel being done by a good smith but it does work. Don't remember the price but way less than $360.Rick.
 
I only use patches and a jag.

With JB Bore compound everything comes out.
 
I had a gunsmith in my area cut and re-crown a barrel for me several years ago for $35. I think he's up to $50 for the same job now.

Also - there was a good article, I think in American Rifleman, by Bryce Towsley, about re-crowning at home with very simple tools from Midway. Looked like an easy enough project. Sorry, I don't remember when I read the article, likely a couple of years ago.
 
An eleven degree crown is not that difficult to cut; even a mechanical klutz like me can manage this one. However, it is worth the price of a good gunsmith to recess the crown. The price is not prohibitive for this work.

Guess it won't chatter if you slow down a drill press alot... but getting the barrel straight is another thing.

Hoppe's. Their copper remover doesn't remove very much copper. I also have kroils and Shooters Choice on my bench. Kroils is great stuff, shooters choice is not bad, for copper, but it could use more amonia. If you are having trouble with you gun shooting, I would try some CR-10 and tornado brushed before I spent $350.00 on a thingey.

I run Montana Extreme Copper Killer and man, it is strong, but if you let it sit a little while in the barrel, your patches will come out bright blue. Love the stuff, hate the odor, although, I am getting used to it! Scotty
 
I tried the Montana extreme.... It took awhile for my nose hair to grow back.. LOL

Think I'll stick with Shooters choice and kroil.... My bores are clean.
 
I have used all the products named and current use the BoreTec carbon and copper removers. Had to switch my jags and brushes. When I first tried them, no ammonia smell, I didn't think they would work that good. So cleaned several rifles after a day long range session. Then cleaned them again using Montana Extreme and Sweets in another rifle. They didn't need the second cleaning. Now I use the BoreTec. May have to open a bottle of Sweets every so often to keep the correct smell in the shop.Rick.
