Just for laughs FG. Shoot some targets the way you hunt. That's useful info to me. I haven't found a bench in the mountains when i'm hunting.
I like to go down on one knee. I've never found a spot that the position didn't work for me.
How do you normally shoot while hunting?
You mentioned your brother in law squeezing the stock. It was about 30 years ago that I realized i was twisting the stock when I shot. I never wrap my thumb over the wrist of the stock anymore. I leave it on top behind the hammer. It helps me hold the gun level, and relieves tension too.
