One of the issues I think is a contributing factor is the Hot Rodder mentality. You get newby's who get into shooting and firearms who look at reloading as way to hot rod their ammo. They probably feel that that since there was no shortage of extra power to be had in a small block Chevy, that ammo is similar in concept. "If a little powder is good, then more must be better." It's never much fun shooting next to those guys
Oh, and no one likes to read the instructions much these days. Not a big problem with that Ikea coffee table. It is a big deal when working with things where the boom is supposed to be a controlled & contained event.
“At the core of liberalism is the spoiled child – miserable, as all spoiled children are, unsatisfied, demanding, ill-disciplined, despotic and useless. Liberalism is a philosophy of sniveling brats.” — P.J. O’Rourke
