90% of my shooting is not limited by my choke but my ability. Under extreme conditions I do pattern guns with special loads to see which load gives me the best pattern.

But choke selection is not that big of a deal if you pratice range discipline. I learned that from my father the first day I hunted. Learn what range you are looking at and restrict yourself to high percentage shots, not sky busting, game crippling and game wasting shots. I watched him at age 90 set "weed markers "" 25 yards out from his spot and then he watched multiple birds fly across his field of fire to see what they looked like at his selected kill zone. Then he loaded up and killed a limit of 15 birds with 23 shells all with a Fox AE 16 I lent him. He never asked about chokes, loads or velocity. Not bad for an old guy. I hope I can go hunting at his age. Heck just being able to go and watch my sons and grandkids shoot would be enough for me at 90.
