Thanks for the information, all who responded.
I just came back from shooting a few patterns.
Now I wonder how I manage to hit anything at all.
The .410 patterns are terrible. I tried using a twenty inch circle and a thirty inch circle. Either way the patterns were terrible.
The gun is an Iver Johnson "Skeet-er" and it is marked O and C
(open and choke). the left barrel is cylinder and the right barrel is full. At 25 yards the open choke's pattern is pretty much blown, only about 20% but the full choke is about 70%.
I shoot skeet pretty well with it as long as I remember to use the open choke on incommers only.
