I'm a bit confused about checking point of impact via pattern testing. As I see it, I spent lots of time getting my shotgun to fit me so that I have the proper site picture (eye aligned left to right with rib, and mid bead convering front bead). I assume that when I pattern test, I should put the superimposed beads in the middle of the pattern board and pray that my pattern is centered where I'm pointed. With that in mind, I've read and had people suggest that if your point of impact is off, you can correct it with a stock/form adjustment. It seems to me that any stock change would just change my site picture and in effect be 'cheating' by pointing the barrel somewhere other than at the target just to correct for a point of impact that isn't 'true' with the site picture. Am I missing something? Is there some way to move the point of impact with a stock adjustment while retaining the correct site picture? It seems to me that my eye is in effect the 'rear site' and it doesn't really matter how I've contorted my body to get my eye in position, but that if my eye is in the same place, the pattern won't move. Thanks in advance for any help.
