I have a Winchester Model 50 12 gauge barrel with a Poly-choke. Would it be possible to remove the Poly-choke and drill/tap the barrel for screw-in choke tubes? The current barrel throws a poor pattern and I would like to replace the existing barrel with a fixed choke barrel or perform the modification to my existing barrel as described here. Thoughts? Model 50 barrels can be found but they are not too plentiful…..

Thank You
