I started reloading only 9 years ago not to save money but because I was unhappy with the results I was getting from commercial ammo. My best friend had been reloading for over 20 years at the time and after trying out some of his reloads, I was hooked. Today I load for 12 different calibers, when I purchase a gun in a caliber I do not have dies for the first thing I do is order a new set of dies even before I pick up the gun. By the time the pistol or rifle is picked up I already have 100 rounds for it made.
The only ones I do not reload for is 22LR, 22 Mag and 12 gauge.
Once you start reloading you will find that you will reload 100 shoot 50, reload 100 & shoot 50 after time you will be supprised at how much ammo you have accumulated and run out of places to store it. As to brass I generally purchase 500 cases and bullets to start with and rotate them as they are used for use again. Each trip to the range will supply me with more 9mm, 40 & 45 cases than I brought in, so I never purchase those. What I shoot the most is 9mm, 45 ACP & 223/5.56 and I can't even start to tell how many of those are sitting on the shelf at home, it would take a week just to inventory them (not sure where I stashed all the filled boxes).
Only problem today is finding bullets to reload, but hopefully this will pass soon.
