I've been following this discussion with some interest because i have a habit of keeping my head too high on unexpected flushes of wild birds. So, perhaps 3" drops would be good for me, at least sometimes.

But this brings me to how do most people actually measure drop? To my way of thinking it is done from the centerline of the bores, but from a pragmatic point of view, I strongly doubt that is how it done in practice by an auction house or online dealer.

I would guess most listed guns with whatever drop at heel and comb are measured by putting a yard stick along the rib and measuring down from that. Is that the actual convention?
