Barrel scoring?

[snipey]

So during my end of weekend cleaning ritual, I notice what looks to be like scoring/crack on my top barrel just after the breech block on my DT10 x trap.

Has anyone experienced this before?

My first port of call was the internet, and various threads saying it's just plastic or lead fouling, however having spent the last 2 hours soaking it in bore cleaner and scrubbing with fine wire wool/scouring pad/various brushes on cordless drill I am less convinced, what do you think

I'm obviously gonna have a chat with Dennis Stepney tomorrow, to check that it's nothing more serious! I hope it's me being paranoid as its a great gun, managed another 100/295 today.

I have had that, or similar, in the past with certain brands of cartridges. Refused to budge despite repeated scrubbing in the usual way. Forgot about it and continued shooting decent cartridges. Eventually it disappears.

Wouldn't have suspected a crack in such a straight line. I expect Denis will push an  abrasive whizzy thing up it and shine it back to new.  :biggrin:

That's the strange thing, I though the same but if I run a small screw driver over it I feels like it drops into it. I know it's happened this weekend; and I have never had a problem with fiocchi before and I have barely put 25 shells through the top barrel this weekend.

I'll leave some oil soaking over night, and see what happens in the morning!

Never seen it before but if it wont budge and if you can feel it then it sounds like a crack in the chrome lining. Don't panic though as I could be wrong and you could just be rubbish at cleaning.

Probably a score mark from foreign object in shot load or wad,it does happen .

Hope it is just a scratch in the surface caused by something in the cartridge... having said that it would have to be something very hard to scratch a high chrome steel ! I don't know how Beretta apply their chrome lining , it is not an electro plating process though I think they somehow incorporate a layer of high chrome steel over the standard steel and it is integral I would really think it unlikely that would crack... but then again the best shotgun barrels made are not chrome lined maybe a reason why?  I don't think you are going to have a problem either way as Beretta will make good if it is a structural problem... if its a scratch who cares not going to effect the gun's performance is it?

edit

Great shooting by the way!

I believe that the Beretta chrome is what is called chrome hardening here.  Not proper plating as the chrome is deposited directly on the steel - actually the deposit is so thin that it is more "in" the steel than "on" it so no "layers".  Like is done with rifles which would roll up blow out the barrel any standard form of plating.

Scratches are hideous horrible things to see in a shotgun bore but fortunately, harmless.

I think you are right Charlie,I am sure I read that the chrome is incorporated into the surface steel of the barrel buy some sort of electrostatic technique?

Yeah - been around for decades

Been to see Dennis tonight, and it is scored; has suggested that something much harder than the chrome was in a cartridge maybe a deformed steel pellet!? Strange thing is it must have been outside the wad to score the barrel in that place!

Anyway quite pi$$ed off, but heh ho!

Can he polish it out ?

He said he could send it to Nigel Teague, to remove several thou; which would certainly lessen it. But ultimately felt it was pointless and I should shoot those few thou out of it! So this is what I'm gonna do, try to ignore it and stop being quite so precious about it, after all it's a tool!

I fully understand your frustration I am a perfectionist I can't live with even minor faults on anything guns cars anything but I am sure a few k through it and it will disappear

I have to say that I was persuaded to try 500 'F' thingy's and found them to be a really dirty cartridge. Before all the 'storage' threads get resurrected, they were stored along with my usual brand and treated in the same way. I had to soak the barrels with solvent several times to clear the fouling. They were mixed Fibre and Plastic wads. Suffice to say I will not be using any more.

P.S.

The Guy that got the other 500 had the same problems. 

 

[balltrap]

Its only a Beretta no big deal!

 

[snipey]

You haven't been shooting those cheap cartridges "Sportsman Smokey Things" have you?

Nope, for the last year I used nothing but fiocchi!

Yeah it is only a Beretta, but I dread to think what it would have done to a lesser gun without chrome lined barrels!

Too late I read it

 

[Eddie Wilkinson]

So if your barrels are scoring, are you winning more hehehehehe :crazy:  

Sorry its one of those days. :hunter:

Hi snipey a pity that happened and at least it is only a scratch on the surface of the barrel.
I know this is a historic thread now BUT I would be very very worried...No extremely worried if you could shoot that mark out with nothing more than plastic wads! I think what Denis was suggesting was shoot the gun it will make no difference and you will forget about the scratch. At least I hope that is what he meant I don't like the sound of a gun losing metal from that area of the bore due to a plastic wad pushing through it.

No don't worried, I didn't think that I would shoot that amount of metal off; he just meant no point in having it polished out when I may as well shoot it until it worn out! Haha
