Tonight, I had aspirations of patterning my KSW 2x12b. However, the pattern plate was a bit dry and there was no grease to add to it. I did make it work for a few shots to confirm that it regulated reasonably (a major relief factor). I shot a few more from the right barrel at only 16 yds and each pattern looked pretty similar to this one. These were aimed shots, not mount and pull.

The hole in the plate is the size of a clay pigeon for reference. As a grouse gun, it seems pretty tight (7/8 oz of #8). What do you guys think? What is a reasonable pattern size at distance X for a grouse gun. 30" at 25 yds is what I"m thinking, and this will probably be quite a bit tighter with too many fliers.
I'll pattern it some more with a couple of loads, but I think I need to open them a fair bit. Measuring the right side I got 0.022-0.024" and the left was tighter at 0.032" give or take a bit.
