Jack, I had been thinking about this for quite some time. I just wondered how the particular load I was using could kill starlings out past 50 yards with regularity. Velocity is right at 1200 fps with about 8000 lbs of pressure. Shooting a mod choke, the gun just seemed to really do the number on those long range crossers. I certainly have never read anything about pressure and how it effects patterns. I think you guys have answered the question well. Thanks
