Open them up if you want. Everyone makes such a big deal if the chokes get opened. Why ? You can't see it and with American guns as far as I know [ limited ] only the 1894 and 1900 Remingtons had the chokes [ number of pellets ] stamped on the barrels. I'm sure that over the years a number of guns had their chokes opened. It's your gun, do what you want with it. Paul
