I reloaded in my basement for 17 years, before we built a new
house, and part of the bargain was I got a 2 story 36'x52',
6" thick walls, insulated, radiant floor heated, bathroom,
and kitchen included in a shop, 250' from the house...So she
has to walk some to tell me about my short comings.
But for those first 17 years, I never had anything dangerous
happen. I had a primer or two pop, on shotgun loaders, after
a shot spill put a pellet in the primer seater. And
technically smokeless powder is not an explosive. It burns
fast, and needs a container to generate pressure.
I think working on cars, welding, and cutting firewood
would be more dangerous than reloading, unless you talk
about careless loaders, that deviate from load data, or
lose focus and over charge a case, and that takes a firearm
apart. I have loaded 10s or 100s of thousands of rounds,
and never had one make a firearm go boom. I had a case
failure in a 9mm pistol, that took out an extractor, and
a magazine, but that was my failure to spot a case with
a crack at the case head(case was a range pickup with a
Glock Smile that I missed on inspection).
Bottom line is don't let any person, dictate what is safe or
not, based on ignorance. Reloading is a very safe hobby
if one follows directions, and pays attention to details.
