Ok this is the second time I've asked this question but left out that the barrel was improvised. Can you shoot slugs through a improvised 18.5" mossberg barrel? I've been told that if I do it will likely blow up in my face cause the barrel gets smaller towards the end. or will damage the barrel towards the end of barrel. No rifling and no choke. some say yes and some say no. I would like to shoot slugs but don't wanna end up in the hospital.
