A good way of ruining a good gun. Having said that. If you want to pay me to ruin your gun for you ,who am I to refuse .
I have seen guns that have been done that have bulged in the choke, as there is not enough metal ther to stand up to prolonged use . If you are having the barrel rebuilt{sleeved} or the gun rebarreled the tubes can be made heavier to take the chokes . This of course can make them muzzle heavy and subsequently affect the handling.
If you have a gun with open chokes and feel you are not getting the range try a larger shot size.
