Choke is a measure of pattern not a measure of bore constriction. I’ve had the same gun and by play with cartridges could get a 1/2 and 3/8 pattern for Norfolk partridge days and a 3/4 3/4 pattern for high birds. Likewise on clays there are cartridges that are good at opening up the pattern faster for those close birds.
Now all that said most people I’ve stood next to (and that’s a lot 6 days a week) miss more because of poor line than choke and in general the choke isn’t the big issue it how they shoot.
My advice pattern a few cartridges and see what you actually are shooting with, then make an educated decision but do spend some time with a good instructor.
