Hi guys, I'm new to shotguns so I have a stupid question for you. When I'm cleaning the barrel is it OK to use a brass (or whatever they're made of) bore brush to clean the inside of the barrel with the choke still inside? I currently have a modified choke in it right now. If it is OK to do is there any chokes I shouldn't use? The reason I ask this is because in my limited knowedge of shotguns I was led to think that the chokes are cylindrical in shape inside, so I didn't know if a brass bore brush would damage the choke when you jam it through. Thanks in advance for your answers!
