Crown damage

[The Pigeon Man]

Hi everyone,

I recently purchased a secondhand rifle and there appears to be damage to the crown.

I would appreciate it if anyone could give there opinion as to whether it will affect accuracy and if I should get it recrowned.

Your help is much appreciated.

The only person who can say with any level of certainty is you, after you have fired it! Why spend money on it if you don't need to? It certainly doesn't look good but then you knew that when you bought it I'm sure!

I had a rifle Re crowned that looked far worse than that, it shot fine, but it looked horrible. Shoots better now and pleases the eye! @brock and norris commented that it looked like beavers had had a crack at it and then it’s been used as a walking stick!!

An old guy once told me u can re crown a barrel yourself using a suitable size ball bearing and some grinding paste never tried it myself but sounds like it may be possible

Damage to a crown doesn’t always affect accuracy but quite often it does. If the rifle is exceptionally accurate I wouldn’t worry about it. If the accuracy of the rifle isn’t to your satisfaction I’d have the barrel recrowned. It’s not very expensive, at least not in the U.S.

Just because it looks a bit "agricultural" doesn't mean it won't shoot. As others have said, if it's accurate there's no need to spend money on it unnecessarily.

The cost of re-crowning is small & worth having done, then you're happy. Mike at Brock & Norris re-crowned one of my rifles ... the cost, £15.00

In short a re-crown is simply a light clean up/deburr of the exit of your barrel, not rocket science,but it will help.

How much are you going to spend on a r

Less than the cost of a box of ammo to check whether it shoots or not

Thanks for the advice. I will see if I can group three shots inside an inch at 100 yards. If not I'll definitely get it recrowned.

 

[brock and norris]

the crown is the last part of the barrel that has contact and therefore influence on the bullet as it leaves the barrel .

I'd give it a good clean with a PB brush and solvent (from the breech end). From the pictures, it's hard to tell if it's actual damage or fouling of some kind.

How do they get damaged is it mainly leaving the moderator on or?

During incorrect cleaning proceedings probably, being a bit too vigorous with the cleaning rod

Take it that’s bad?

I can't see the photos too good but it looks like it was threaded using a live center, see how the actual leading edge into the crown is a bit mushed along with that little dent you can see?

I've seen a rifle where the bloke kept the on (told him not to) and it leads to a rounded pitted mess.

From a machinist pov that should be a nice clean angle perpendicular to the bore.

Id shoot it and see how it goes worth a shot! At the same time a good gunsmith is about 25 to 50 quid for a re crown, so it shouldn't break the bank.

I'm not a gunsmith! but that's my 2 pence anyway

@bhawk that looks like pitting, either the mod was left on, or the no one wiped the barrel with oil after removing the mod
