I've never bought a gun just because I had a lot of ammo in that caliber but that would be a excellent reason to buy it. I have pretty much rounded it off to buy calibers that I'm set up to reload. 38/357,45 ACP, 45 Colt, 9MM. I got rid of the .40 gun and dies etc, but I would buy a 44Special if the right deal comes along, I have some brass for it.
