Yes. Some posts on here can be tongue in cheek, but I want zero to do with any porting on a shotgun. They technically create the same amount of noise, but instead of blowing it out of the business end they spread it all around. I'm a big advocate of ear protection, but even with ear pro in, I can discern a large increase when shooting next to a ported gun on the trap field. I wouldn't want to hunt with anybody who had a ported gun. Porting on a shotgun has zero effect, the pressures don't get high enough for it to make a difference. I also think having a shotgun barrel that looks like Swiss cheese is ugly as hell. The ports collect carbon, a pain to clean so I've been told. They sell a decent amount of them so some people like them, I just can't figure out why.
