thanks for the welcome!
I'm in the triangle, and a Duke football fan!
Been to Lake Lure a couple of times.
Had my SBH lock up yesterday at the range. I just got it back from Ruger yesterday. Somehow a grip frame screw broke so that the stub was below the frame surface. I tried to remove it with a reverse twist drill bit, but it was like operating on a grandchild.
Ruger returned it yesterday all fixed up. Shot 12 rounds of semi-hot home made, it seemed fine.
Started to load a third and the cylinder stopped turning after 3-4 bullets. I removed the cylinder several times, then after loading and shooting three at a time, I gave up.
The base pin latch had always been a pita (bought the gun used last August). Now it was stuck in the open position, wouldn't slide at all.
I brought it out the the range armorer, (he looked younger than the SBH) and he told me that old timey pistols were out of his lane.
Did a little searching and found this forum. I discovered what that little itsy-bitsy sprung pin on the end of the base pin was for.
I saw how the safety transfer bar would hang up on the firing pin, preventing the hammer cock and cylinder rotation, unless the base pin was locked in.
Head space might be an issue, but it's not a protruding primer (very careful about seating primers) All the parts are the same, so it would be strange to suddenly lose head spacing.
The hang up seems to have occurred when loading the fourth round, which suggested a cylinder misalignment.
Could be case length, I don't trim the case length, but it seemed like it was something about the base pin.
Took it home, ground up an old screwdriver to make it into a forked screwdriver, removed the ejector, base pin, base pin latch, cleaned everything up, put it together and now it seems to load.
When I had everything apart, I realized that the base pin has a ground out half moon on the stop collar. This allows the base pin to slide along the barrel, and keeps the base pin notch lined up to engage the base pin latch. If the base pin was cocked a bit, it would hang up on the barrel and not slide.
I'm writing all this detail for anyone like me who might be having a similar issue.
Not sure if it's solved, but I have a better understanding of how the gun works.
I love the gun, I don't like all the jewelry sized screws, pins, and latches.
