I have a number of 16s and hunt with them almost exclusively. (When traveling, I use 20s because of ammo availability issues.) My main gun is an Army & Navy, w/2 1/2" chambers, 30" bbls, made in 1896 by Osborne. The gun has an absolutely tight lockup.

While one can't get 2 1/2" ammo in the typical local gun shop, it is easily available over the internet. I generally use Gamebore shells w/ fibre wads, and shoot them in all my 16 bores, even the ones w/ 2 3/4" chambers. In the overall scheme of things, cost of ammo (except for expensive exotic non-tox, e.g. NICE)is irrelevant.
