Angry Can anyone else see a crack in the crown

Hello, I am new to the forum. I have been shooting for most of my life and just recently purchased a new SP101 hammerless. I have had it in my posession for just over 3 days and decided to take it to the range today.

I did a full inspection of the gun when I purchased it from Cabelas and it had no blemishes. I later cleaned the gun and prepped it for the range, going over it with a fine tooth comb and the only mark on the revolver was from turning the cylinder.



So today I am at the range and fire a box of 50, 38spl JHP +P throught it and 25, 38spl wad cutters and lastly 25, 357 mag Win JHP.

When I returned home from the range tonight I started cleaning the revolver and noticed what looked like a crack in the crown of the barrell where one of the fluted riflings had ended. I can absolutely say this was not there last night when I prepped the revolver for the range.

Can anyone else see these fractures. One goes vertical from the opening into the crown and the other horizontal along the raised rifeling of the crown.

Should this go back to Ruger for repair?

Diagnosing something like this by pictures is really tricky, and really open to error.

That being said, it appears to me that what you are seeing are just tool marks. If you look at the marks between your arrows, you will also notice that the blemish continues past the right hand arrow. This is typical of the marks that are made from a dull tool.

Admittedly, your crown is much better looking than mine, and my gun has been fed thousands of rounds with no problem.

However, if you are worried about it, talk to Ruger, or take it to your local ‘smith for his opinion. Your view, under various lighting conditions are much better than any picture you could post.

Okiebat, I'm with Varmiter on his caveat that inspection by photos is not perfect but you did post some great photos! I also agree with Varmiter that the potential issues you're seeing appear to be residue of a less than sharp crowning cutter. I would personally continue to shoot it and occasionally inspect for change in appearance of the indications you're concerned with. I have a crown lapping tool and, if it were mine, would lap the crown to remove all of the tooling marks to see if these indications go away. If they remained after lapping or without lapping "grow" with continued use, then I might call Ruger and email photos but I kind of doubt that these indications are stress cracks. If these indications do turn out to be stress cracks, Ruger would surely warranty barrel repair or replacement at a later date.

Looks like casting marks to me. My GP has some of that going on too.

I'd go with the above advice, though you might possibly have it "magnafluxed" ... or if you know some pipe welders, have it xray'd ... JL

I appreciate the feedback and the compliments of the pictures.

I will go ahead and put a few hundred more rounds through it and see if it expands or remains the same.

Wish me luck....

Definitely toolmarks, at least from the photos. Good inspection, though! Might have a gunsmith smooth that out for you if you're worried about a nice, uniform crown.
