Rifling the chokes would be an interesting venture, but - the 32" barrels are VERY long and probably cross too much for ball shooting. This is due to the wide receiver and touching barrels at the muzzle.

Only shooting will tell for sure.

The AYA 10 bore Matador I used on geese many years ago(before steel shot) was deadly, after I worked on the too-tight chokes. 96%X94% for left & right barrels, 2 oz. lead #2's, 3" hull. 80 yard goose gun smashed them.
