I started out hand loading shotshells with MEC loading equipment.
I progressed from that to pistol calibers. I had a Ruger Single Six in .32 H & R magnum. Ammo wasn't plentiful and was pretty expensive for me & I was pretty conservative in using it. Started out with a Lee Challenger Breech Lock Single Stage kit and .32 H & R magnum dies. It all worked so well, I quickly added dies for .38spl/.357 magnum and then to .44spl/.44 magnum. Now I also do 9mm, .243 Winchester, and .45-70.
I still do all my center fire reloading with Lee dies and the Lee Challenger Breech Lock kit that I started out with.
