Back on topic. The single six is built like a tank. (that is an analogy) ::)I have not had any problems with mine except the shroud screw coming lose. Lock-tight fixed that.
My cousin bought his a few weeks before I got mine, both are the old 3 screws. I want even attempt to tell how good we got with those things. At least to us.
One thing we would do is go shoot at the county dump. They were filling in a hollow or valley so to speak. This is in the mountains of Western North Carolina. We could shoot a far distance across the dump and did a lot.
We would fill tow sacks or burlap bags with small jars like mustard jars and such and take them to the wide river behind his mother in laws house.
It was fast and had some good rapids with big rocks. We would take turns and go up the river 50 yards or so and throw in six jars. One would stand at the rapids and when the jars got in the big rocks and rapids we would start shooting until we missed then we would change. We had to start taking turns. Even though they were moving pretty fast and bouncing we could hit them. I bet we threw in 30,000 semi truck loads of small jars to shoot.

To the purist: when the glass would break in the fast rocky river by the time the glass had worked its way a 100 yards down the river it would be as smooth as a small stone with no sharp edges. Most of it was ground up in the deep holes of the rapids.
This is some of the fun you can have with a good reliable gun.
