My daddy was a 16G fan but that was in an area where they were about as or maybe even more popular than 20s. Now, being out in the broader world, I have to notice that I've only known one local store in a city of one million that stocked 16G ammo and they went out of business, also taking all the over the shelf 28 gauge shells with them. Both 16 and 28 gauges have what are usually considered cult followings and go in an out of popularity, as I'm told, but as far as 16G goes I've never understood why a user wouldn't pick a 12 or a 20 and be able to buy shells almost everywhere. No doubt that's just me, I shoot a 12 just because it's the most popular.
