Since you asked; now is a great time to do some substantive research into the vagaries of shotgun patterns i.e., spreaders, specifically.
Wonderful things are to be said for plumb bago(sp?) [flattened shot] or any of a number of dif approaches [inclusive of learning how to shoot as Murphy & Wonk both only too well grasp], but you will have to make yer own determinates.
Leave the chokes alone and open a new window to yer understanding instead.
Its quite possible to have both worlds w/o choke alteration. Amazing! Yes? No? Find out for yourself; odds are in your favor for a most pleasant surprise.
kind regards, tw
No offense intended & I'd hope none taken; it simply strikes the nerve at the very centre of things relevent to yer question.
