I have an 18" .920 heavy barrel on my 10/22 rifle that used to shoot very, very well. A few months ago, the rifle took a fall off the bench and dinged up my scope, and the accuracy went away. Fast forward to this week- I got a proven scope back on it and accuracy still sucks. I thouroughly cleaned the barrel and noticed a little ding right on the crown. I am 80% sure this is what is killing my accuracy. My issue is this was a fairly inexpensive barrel. I doubt a new one at that price point will shoot as good. I was shooting under MOA out to 100 yards before this and I hate to can it and try another cheap tube. I'm thinking it'll be $50-$75 for a recrown plus shipping as we don't have any gunsmith here on island. Is this barrel worth the $100 gamble? Should I just pony up the funds for a quality barrel? $250-$300? Any easy fix other than doing a Larry Potterfield crowning job with a brass screw and lapping compound? Thanks for any insight.
 
Re: What to do with a damaged crown?

Thanks for the replies. chpprguy has generously offered to recrown it for me at no charge other than shipping. The willingness to help from other forum members still amazes me at times. Hope you like smoked salmon, cause a package will be headed your way!
 
Re: What to do with a damaged crown?

I do like salmon....
If you lived close by I would tell you to bring a few beers and we'd fix it up....same thing, you just live farther away...

I would love to see if this actualy works worth a damn...
 
Re: What to do with a damaged crown?

I have the PTG crowning tool/cutter with the pilot inserts. I would be happy to recrown it for you as well. I've done several old 22's with it and it works well.
 
Re: What to do with a damaged crown?

I was going to offer to recrown for the cost of shipping but chpprguy beat me to it. Not a big deal, and its worth 5 minutes of my time to help out a fellow hide member. Good luck!
 
Re: What to do with a damaged crown?

I friend recut my crown with a 45* break between muzzle face and bore, The break goes as deep as the bottom of the groove and no further. He used a Brownell piloted cutter. Accuracy is excellent, and the break angle makes the crown face intersections a lot more durable.

By the way, this is the actual meaning of the term 'Muzzle Break" and the reason why I get kinda disappointed when I see folks mis-substituting the term for "Muzzle Brake"

Yes, you can repair acrown by yourself. For an inexpensive barrel, I might actually be tempted to try it, as an experiment. But for most 10/22's, I'd just buy another barrel of the same length. It's not rocket surgery...
 
Re: What to do with a damaged crown?

Thanks for all the replies. I really thought about just buying another $100 barrel, but this one was exceptional. I have shot several 10/22's with inexpensive barrels and several with very good barrels and it would take a $250-$300 to do what this one used to do. chopprguy is handling this one for me and hopefully it does the trick. If not, I'll have to pony up for a Volquartsen or a Kidd. The damaged barrel is a Butler Creek if you can believe that. The same company that sells the scope flip covers. I believe they use Lothar-Walther blanks. Thanks again everyone!
 
Re: What to do with a damaged crown?

the brass screw and lapping compound really does work. There is a video on youtube from midway showing how with normal at home tools. Larry Potterfield walks you through it. I hope this helps.
 
Re: What to do with a damaged crown?

I have done the brass ball and lapping compound on another barrel and it worked ok, but didn't give that perfect star blast pattern on the muzzle. Some people have had decent success doing it that way, others, not so much. I would have tried it as a last resort on this barrel but I'd rather have it done properly on a lathe. I really need to eliminate as many variables as possible to figure out this loss in accuracy. So far, I've tried several scopes, bedded the barrel channel and pillar bedded the action, bedded my scope rail, and tried 11 different brands of match ammo. If Eley Tenex, Lapua Center-X, and Lapua Midas are shooting 1 1/2" @ 50 yards, something's bad wrong!

Chpprguy and Kenda are both class act guys to offer your services for free. It's funny how people on here can bash each other one min and fix the gun for them the next. I just wish that the rest of the world would just get along and we wouldn't have to deal with the crap that we do. Tommy

best advice.


<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Sledge Hammer</div><div class="ubbcode-body">To me it would not be worth the $100.00 gamble when you could buy a very nice barrel for $175 and it is brand new.

I had a barrel from these guys and it shot great.

If this is a gun you feel attachment to, pony up and email Kyle at brux barrels. If not, sell it to some poor sucker as a fix me up, and buy another.
