The reason the shotgun area isn't going to be split in a similar fashion is simple -- it isn't busy enough to warrant it.
The handgun forums were the first ones that were split, over a decade ago. It was done because a single handgun forum was just too unwieldy.
On an active day a thread could be posted, and end up on the second page, within an hour, and on the third page, or farther back, in less than 24 hours.
The posting rate was simply too fast for either staff or members to keep up with.
We were getting to that point with a single rifle forum.
If, and ONLY if, the shotgun forum becomes as busy as the rifle forum was a month ago, then that's when we'll consider splitting it.
