Re: Shotgun Choke question
As all shotguns pattern differently ans fit each shooter differently, to find the best combination you will need to spend a bit of time at the range with sheets of paper seeing what works best for you. There is no "absolute" bore on a shotgun, size can vary a few thousandths and the shot size and charge size can affect what constriction your choke actually produces.
Shotguns fit different shooters unequally and the point of aim can vary between shooters of the same gun.
Confusing? Sorta, but your best bet is still to try it yourself and find what you feel works best.
