I have an older (late40's early 50's) S&W revolver. I would like to find a second cylinder and ream it to 22 mag. The modification must be able to be relativaly easy to revert back to original condition.
Is this a sound modification or am I crazy?
A word of caution:
These older S&W revolvers were NOT properly heat treated to take hotter ammo like the .22 Magnum.
While a newer cylinder might have the correct heat treating, the FRAME doesn't.
Although the revolver probably wouldn't blow up in your face, the frame would be quickly battered and ratchet peened.
In other words, you'd spend money on a revolver that would quickly be ruined and rendered unfireable.
The .22 Magnum barrel's bore is larger than the .22 LR. Shooting Magnum ammo down a 22 LR barrel will stress the gun even MORE, and is certainly UNSAFE.
Bottom Line: I doubt ANY competent gunsmith would even consider such a conversion.
K, thanks faris...that's the info. I was looking for.
