Years ago I passed on 28 and 16ga guns because even though I love to reload hulls for these gauges were hard to find let alone ammo! I have a 22-410 and my kid has a little H&R 410. It never use to be hard to find 410 ammo not big selections but everyone has some. Now all I can find are 12, 28, 16, and 20 in that order at local shops! What is the deal I never saw so much 28 and 16! I figure it’s because no one is buying it? I always though popularity would go 12, 20, 410 then way back 28 and 16 he’ll I see more 10ga on the shelf than 410
