Uberti 357 Magnum El Patron 1st Outing. Wow.

I'm having alternate ideas on the source of the half mooning. I'm thinking its caused initially by abrasion while in the box (no padding) it came in. Then gets added to when taking it in and out of the box and during transport in the box to the range. That the burn covers it up during shooting and then the mooning gets noticed during cleaning.

Interesting to hear that all of you are seeing the "half moon" burning of the end of the cylinder. I've never owned a blued revolver, so I'm guessing it's been there on my stainless cylinders in my past 357s. I'll consider them character markings.

To my eye, it's not an abrasion type of issue. And, it if were a shipping-related thing, it wouldn't explain how it's so visible on all cylinders and is so uniform on all cylinders.

No, this strikes me as heat-induced. Since mine didn't come through Taylor's, I'll try to figure out who I might send a picture to. If any of you other UB owners have a thought, please let me know.

I"m not worried about it, and, given the number of us who are seeing it, seems like it would be hard not to call it "normal," but it would be nice to know how normal, wouldn't it?

The pic below is of the cylinder, post-cleaning, where you can see an example of where the aforementioned blasts have taken the bluing off of the front edge of the cylinder (in the same spot in every chamber) in a sort of half-moon shape.

This pic is of my .357 Police revolver. This spot shows the "worst" chamber on the cylinder. The other chambers have much less, one is close to nothing but a thin, straight line at the very front of cylinder. Have shot 125 rounds so far, exclusively Cowboy loads.

I've called Stoeger Industries Service Department a couple of times with some technical questions about this revolver. The tech was very helpful, and explained things well to me. Actually, you'd call the CS of whichever company your revolver came from: Stoeger or Taylor & Co.

Not sure what causes it. But since it will probably happen regularly, I'm not going to have my cylinder re-blued anytime soon because of this issue.

BTW, on my blued Russian .45 Colt there are some similar markings, not blossoming into the "moon shape;" rather they run only in a thin, straight line at edge of cylinder for each chamber. Interesting.

I've looked at the "contact us" page of the UbertiUSA website, and there doesn't seem to be a provision for adding a photo, so I might call them and see how far I get.

Do NOT stress about that half moon markings on the cylinder. It is common to many revolvers, both double action and single action. I get it on most of my revolvers, in fact. Not a big deal and not something to waste time on with calls to the manufacturer. It's simply a by-product of gas escaping from the cylinder gap. As long as the gun is not excessively spitting lead or fouling up, abnormally, at the forcing cone, just clean it and go on.

Shooting low and left is most commonly caused by squeezing your hand while pulling the trigger. You must NOT change the pressure with your grip in any way as you squeeze the trigger. Only your trigger finger must move, never the entire hand. Dry fire your gun, exaggerating the squeeze in your grip hand and watch the sights as you do it. One helpful hint for getting accuracy out of plow handle single actions, is to place your pinky finger under the bottom of the grip. This puts your hand in the same position for every shot and it actually makes it more difficult to squeeze that grip hand. Give it a try.

Thanks, NCG. This is for sure something that is not that stressful to me. I barely notice this shooting "scars;" just clean the revolver after range time, then head down the trail. But I did find it to be an interesting chat.

There has got to be some gun wear & tear since we "explode" that much pressure with each round fired. The cylinder on my Russian is particularly nicely marred and scarred from shooting. My next range visit will bring me well over 300 rounds out of that revolver. Also dis-assembly/re-assembly of the cylinder and frame writes its own history. The very first time I dis-assembled it for cleaning I ran a scratch from the front to rear of the cylinder....and that wasn't the only time I did that! Took me a while to learn how to move the retaining plate sufficiently out of the way to mitigate doing this. Taylor & Co. said they can re-blue my cylinder for around $20. Almost sent it in, but realized I would probably repeat the scratches fairly quickly. So it remains as is.

One final comment on this Russian. Of all the revolvers I've cleaned, this one has the least dirty and easiest to clean forcing cone of all others. Kind of have tried to figure that, but don't know enough about how a forcing cone and cylinder are built and may impact each other. I do always pay close attention to how it shoots, so that's at least taking care of the revolver.

Might do a little reading about forcing cones today. We're heading into another winter storm later in the day and overnight. So I'll be hunkering down and just watching snowflakes fly!

Adding to what has already been shared...

On some Peacemakers that have been shot a lot you will see what looks like areas on the front corners of the cylinder right where the chambers are, places where it looks like the blue has come off. They will appear gray color and are on the front end of the cylinder. This discoloration is really just lead deposits that seem to have wrapped around the corner and extend on to the outside of the cylinder. These deposits are difficult to remove without actually rubbing through the blue finish.

I figured it was something like that I was doing. Thanks for explaining the mechanics of the behavior and how to practice overcoming it!

I spent last evening dry fire practicing and examining. Looks like when I pull the trigger all my other fingers twitch/clinch in unison. Takes a lot of concentration to just twitch/squeeze my trigger finger without the rest of my hand doing it too. Like that's the way my nerves are wired in my hand. I did do the pinky under the grip and that helps. But it also left the inside of my pinky sore where it was chaffing on the bottom corner of the grip. Again thanks for the help. Will keep dry practicing and when I have more ammo see if I can do better for real.

Looks like you had fun! I have found that my revolver (.357) is more true to aim at least 15 yards from a target, and my Derringer (.38) is true at no more than 7 yards from a target. Along with the others advise, I would try opening up the range some just to see the point of impact also. When certifying with a .38 revolver, we typically stayed within the 15-25 yards range.
