Wow, people are so quick to dismiss this. Anyone who has machined a long piece of steel rod in a lathe will know just how bendy it can get. Long thin rod with weight on the end, unsupported, it's going to bend a minute amount. Not so much with a short fat barrel.
I have experienced POIs I can't explain with chairgun or rifleman's, improved-rifleman's, sierra approach oand other computer modelling. Maybe it's just my gun.
On the subject of the rifleman's rule, does anyone have an explanation for why it doesn't work with airguns? The theory seems reasonable.
