I want to take my Tristar Cobra Pump 12g. out to the shooting range. The range only allows you to shoot slugs from shotguns. Some people I speak to say not to shoot slugs through a barrel that uses choke tubes. I also have an H&R Pardner 12g. that I can use, but I want to put the Tristar though the paces. So, my question is......can I shoot slugs through a barrel that uses choke tubes? and if so, which choke should I use? Forgive me if this seems like a stupid question, but I am here to learn. Thanks.
