Nice fireball!Yes some, but it didn’t seize the cylinder, just made it a bit harder to cock the hammer for the next shot. I didn’t clean and dry the chambers though, will have to do that.
Some evidence of high pressure and setback : flattened primers
Why is the barrel marked ".22 Magnum??"
Do keep the chamber oil-free, I recall seeing some inserts for firing .22 rimfire [LR or WMR] but can't recall if S&W made them or other supplier.
