I've been reloading and shooting for 64 years. With some exceptions, I'd have to estimate that I shot my own home cast bullets probably 85 percent of the time in my reloads. That's for rifles and handguns. I loaded 175 gr. cast in the 30-30 for deer and they worked just fine. Same bullet in the 06 made for good target practice. Worked just fine in the .308 as well. I almost never use factory ammo in my handguns. In fact the only factory handgun ammo I have right now is what is in my CCW gun. Frankly, I would much prefer my hand load with a 158 gr. cast SWC.
There is something about being able to make your own bullets. If you have a supply of primers, the proper powder and the metal to cast, this bring about a certain feeling of independence. it's a good feeling.
