I bought so much ammunition back in the 90's that I thought I was going crazy. When my wife and i moved into our current house it took two trips in an F250 to move my ammunition and I have added more in the years since. Unless I just started wasting it, I will never use all of it. That being said, I would still consider the availability of ammunition and loading components if I were considering the purchase of a new caliber firearm. I still shoot frequently and concentrate on the quality of my practice sessions instead of the amount of rounds I fire.
