I was having a discussion with a Hornady employee regarding use of their saboted slug offering (SST). He mentioned the fact that there are many shotguns in use with 2 3/4" chambers because that was the standard for so long. I agree, but I tend to suspect that for those hunters who use a rifled slug barrel, they are using guns with 3" or 3.5" chambers more often. So I am posting this poll to try to determine this answer.
