Well, excuse me Mr. McAskill! I absolutely disagree with your opinion that it's human nature to disregard warnings to life and limb. If what you say is indeed fact, we would have hundreds of thousands of reloading accidents reported, which isn't the case. I give the shooting world much more credit than you have.... I believe that 99.9 % of the reloaders and shooters heed all the warnings and stick with recommended reloading practices.
And as far as reloading the aluminum cases, they crumble, collapse or split if you try to size them. The heat destroys the elasticity of the metal, something the manufacturer thought out quite well. You don't have to worry about the primer, they destroy themselves, (the case) before you get that far.
