Who has ever ruined a barrel or crown cleaning?

I don’t think he’s on this forum but I remember Travis (Florida Bullfrog) telling us how he ruined his Marauder barrel. I’ll see if I can find it this evening. 

Also, I’m pretty sure Sean Pero reported seeing it a number of times in his gunsmithing practice. 

But yeah, I suspect one has to work at it to do enough damage that it demonstrably impairs accuracy. However I’ll draw a distinction between a crown damaged by cleaning and one improperly cut by the factory. I see that garbage way too often.

Much appreciated. I do know of bullfrog he help me with my Flex he's over on GTA I believe. I'm thinking it's a Myth that you can screwup a barrel or crown by just cleaning it. Might be one for science busters
 
I've used jointed aluminum rods, with brass jags, both soft metals.

I'll clean bore to breech, or vice versa. 

I even did my own crown job recently (on a $15 barrel) that turned out terrible, and the gun shoots fantastic. I havn't taken it past 20 yards yet, so who knows, but it is a pistol. 🤷‍♂️ Shoots one hole @20 

My 1911 has huge pits in the barrel, came like that. Shoots great! 

Idk how anyone messes up a barrel, to be honest, haha.

Only gun I've had trouble with is my .177 barrel. For my Novastar. I've heard reports of the bores being oblong 🙄 but havn't looked close at mine. Got a non-hatsan barrel for it
 
I had to use sand paper to smooth out my marauder barrel and was super worried about it after reading the horror stories online. A few of my strokes went too far and touched the breech. My gun shoots Lazer accurate now. I know you can mess up your barrel but if you do just buy a brass screw and valve grinding compound. In my case I didn't even need to do that. You probably have to work pretty hard to screw a barrel up. Jmo

my buddy did this to his Vulcan barrel a few weeks ago. He claims his wife walked by and and bumped into him but I know better. He must have really jammed the rod down the bore to gouge it this bad. I told him stay off the Jack Daniels until you’re finished.

FWIW, I’m looking at that photo and it just doesn’t compute. The rifling is sheared off. The force required to do that would crumple a cleaning rod like a Dixie cup. Any idea how he managed to do that? I’m thinking you’d have to take an oversized gauge pin and hammer it into the muzzle to shear off the rifling in that manner.
 
 Zonk You just couldn't wait?!!😄

Yep that was me, and for the life of me I'm not sure how it happened. I have cleaned the barrel the same way each time, same rod and brush and never noticed any damage until this time.

Fortunately i have a buddy (not Zonk💩) who builds custom rifles and he was able to re-crown the barrel and it is back to shooting pigeons at 96yds. I had Charlie Frear order me a barrel while i was waiting to see if the barrel could be saved.

When i spoke with Charlie he said to never use a rod in these barrels, they are made from a milder steel in comparison to PB barrels. I will now be using Crown Saver pull through from here on out. Charlie has been great through this process, and i will be getting a new barrel lapped and polished from Charlie.

So to those out there who are using a rod be xtra careful with these rods. I never thought and aluminum rod could do this either. Lesson learned

Wow, I’m glad you got it fixed. I’m still interested though in how that damage was caused by a cleaning rod. An aluminum one at that. For example if the blunt end of the rod caught the end of the rifling, it should have taken a tiny bite from the aluminum and skittered on past with no significant damage to the steel. That’s a head scratcher.

Was there a steel-sleeved brush on the end of the rod that smashed into the rifling?

I really think it was the connection to brush. I noticed it after a huge deterioration in accuracy, when i looked my jaw hit the floor. as careful as iv'e been cleaning, it only takes one time of not paying attention and things go south.

The other views of the crown really had me confused, even Zonk was confused.
 
I've used coated cleaning rods for many years with no problems. I don't buy the idea of "stuff" getting embedded in the coating and causing damage-just keep it wiped off and check it regularly. It seems that even with those rods, the critical (potential damage area) is the transition junction from coated rod to fitting, whether a jag or brush.

I'm with you what the heck caused this mess? That looks like something bigger then a rod did that damage. A rod wouldn't possibly take up that much material space plus rods are round from all I've ever seen. Someone isn't telling the whole story here. 
 
Why wouldn't you believe the story? I can't explain what exactly caused it , but it happened.

I didn't say I didn't believe you I'm saying you left out a whole chapter of the story 😂😂😂

I wish I knew. I keep going over it in my head, and I am not getting an answer.

I think it was the rod to brush connection, but I can't recall getting it to hang up to cause that much damage.

The timing to your post was perfect. When i saw it up yesterday I was thinking "here we go", this should be good.

Thanks
