I picked up my Ruger LCR yesterday and put 50 Winchester 130gr. FMJ rounds through it. After cleaning the gun, I noticed this:

Flame cutting? Tooling mark? Anybody else experience this with their LCR's?

keep shooting, then you will see a flame cut, that might be just the beginning

I'm no expert, but that does not look like flame cutting to me, a simple tool mark is what I would suspect.

I think that flame cutting would occur a little more on the top strap and not where it shows now. Also, it should not happen with only 50 rounds.

Should not happen with that low of a round count.

I have broken-in 5 different .357 magnum revolvers of various makes. A least on the ones I have had, you start to see flame cutting around 800+ rounds.

I didn't want to make another thread so please pardon my lack of knowledge, but what exactly is "flame cutting?"

Umm, no. :)

Flame cutting - so, revolvers have a cylinder gap. Every time you fire, some of the blast escapes through the cylinder gap - this is the small space between the front of the cylinder and the forcing cone on the revolver. Eventually this escaping hot burning gas starts to wear into the top strap, hence the name "flame cutting".

I assume you mean this spot?

Not flame cutting. The finish is still intact. Looks like a tool mark that was made prior to the finish being applied.
I've put over 2k rounds through mine without a problem. That spot gets alot of wear. The finish on mine started to erode just above the forcing cone after a few hundred rounds but no flame cutting yet.

Yessir, that's the spot I'm talking about. A member on another forum also mentioned that it's most likely a tool mark because he only has 30 rounds through his and has the same mark on his gun.

I suppose I can breathe a sigh of relief!

It looks like tool marks as other have said, but you can get flame/gas cutting with only 30 rounds. I have flame cutting with only 21 rounds out of my 357 mag.

No evidence that flame cutting will compromise the strength of the topstrap, regardless of extent. Forget it, and shoot.

30 rounds certainly is not going to induce flame cutting, IMHO. I can speak from my own experience, I have not seen any evidence of flame cutting over the past 10+ years in revolvers I've used, definitely with more than 30 rounds through them.

If you want to see flame cutting do a search for 357 maximum shooting 125gr bullets.
