I started reloading in 1979. Back then and before, NOBODY mentioned the worry about "Double Charging" your cases. The actual advise was "Pay attention!" or "Don't allow distractions!" If you can't pay attention, you have no business reloading ammunition!
That being said, Reloading is safe, fun, and may or may not produce savings. I started with a Lee Loader in 303 British and a hammer, sitting cross legged on my basement floor. In 3 boxes of ammo, I had paid for all my equipment and components, so the next 40 rounds were absolutely free! If I had stopped there, I would still be about $18 ahead of buying 100 rounds of sporting ammo! BUT NO, I was bitten by a bug that is "Itching" me every day until I die! I now load 117 (or a few more) different cartridges. My newest loading bench has 3 different presses for metallic cartridges, and I have 8 shotgun presses. I have multiple collections of "Antique" loading devices. As well as two presses I set up on a Workmate, to help with "High Production" projects.
Of course selling my sub-machine gun a few years ago did away with to 20,000 round years of 9mm! But when I'm active in Cowboy shooting I run 8000 round of 45 LC and every year runs about 5000 rounds of 45 ACP. Plus I load several thousand rounds of shotgun ammo a year.
I tell people, "I can quit any time I want!"
I would advise you to sell your equipment, and save yourself!
Then again, you can stay here with us and be "One of the Cool Guys!"
