Author Topic: Flame cutting on Remington revolvers (Read 708 times)

Go'day,

Has anyone experienced flame cutting of the cylinder pin on Remington BP revolvers? I have two revolvers with about 4 thousand rounds through each and both have quite severe flame cutting on the cylinder pin. I only noticed it the other day as it's difficult to see unless you take the pin out of the frame. My normal load is 26 grains Wano BP, cornmeal and a .454 soft lead ball.

Just a thought. I have no flame cutting on any of my guns. Could your corn meal be scouring the rod? What is the cylinder gap between it and your forcing cone? My Remmy hasn't shot 4000 rounds, but the rod isn't even marked yet. I'm just a bit surprised.

Cyl to barrel gap is about .006". It is not the cornmeal scouring the pin, the pin has been flame cut. The cut is aboit 1/64" wide and is round bottomed and about 1/32" deep. Apparently it only starts after more than 1000 rounds have been fired and seems to progress up to a point where it then no longer gets any worse. My guess is that at that point the flame point is no longer hot enough to erode steel. I have ordered two replacement pins from DGW but will continue to watch my guns carefully to observe how the flame cutting progresses.

It's not that the flame is cooler. What happens is the area being gas cut gets "work hardened" and the gas cutting process stops there. I've seen this happen to the top strap of my Dan Wesson 357 maximum and that's how it was explained to me by several smiths. It's also explained in some reloading manual that include high pressure silhouette load
data. :-)

Although, we're using BP, the process is the same.
I have several 60's and 51's that show the same type of gas cutting on the cylinder pins and none have progressed beyond a certain depth after so many rounds. About the same was what your's is. Your having gone through 4,000 rds before noticing, the gas cutting probably stopped a long time ago. :wink:
