polishing a fixed choke barrel?

[trackerbucky]

I'm setting up to take the young son of a friend hunting this spring and all I have for a 20 gauge is a single shot Beretta companion. I've patterned it and it's good to about 25 yards.  Has anyone here ever polished the barrel on a fixed choke 20 ga, and if so did it improve the pattern? 

Thanks

I'm curious to know this as well. I have a 12Ga fixed that I have been considering polishing.

I may try it but I'm worried I might open the choke up by polishing it making the pattern worse.

I would deep clean it first and see how it looked and go shoot it. If it ain't broke, don't fix it...

The bore looks nice and shiny.  I'll try the deep cleaning and pattern it when I get a chance.

yes you can polish a fixed choke barrel with NO problems. polishing will not hurt any regular choke at all. it will dull wad catchers or ports designed to slow the wad. but it has 0 effect on the choke itself.
deep cleaning is just that, cleaning . it does not come close to comparing to polishing.
i have polished deep cleaned barrels and have proven my point.
