Actually, my point is that most manufacturers list their 12ga magazines’ capacities based on 2 3/4” shells. That’s the standard length. 3” and 3.5” are Magnum shells. Anything less than 2 3/4” is considered 12ga Short these days.

If 2 3/4 inches is a "round", that's fine. Someone else said they had an 8 round magazine on a short-barreled shotgun.

I suspect those are the 12ga Short variety. But does that count as a "round"? If it does, then will they start regulating magazines according to how many of those it will hold?
