I share the same sentiment as
@Litetrigger - I know reloaders/hand loaders who can and do load to as high or higher standards than I, so shooting their loads is assuming no more risk than shooting my own.
Many folks do need to look themselves in the mirror on this topic; most folks don’t build their own cars or do their own mechanical inspection on airplanes when they fly for work or leisure, most folks aren’t harvesting or processing all of their own foods, or compounding their own medicines, purifying their own water or even validating its quality… most folks aren’t proof testing their firearms nor manufacturing their own… most folks put faith that elevator inspectors have done their job properly when they enter an elevator, and that architects and civil engineers have done their jobs properly when they drive over a bridge. I’ve never seen anyone inspect an ocean-faring cruise ship, let alone construct one of their own hands before being willing to embark… folks don’t blink twice when buying factory ammo… Folks put more faith in total strangers and high throughput automated processes for FAR higher risk opportunities every. single. day. than the menial task of reloading.
Folks also ignore that mistakes happen even when their own hands are operating the press, and failures can happen for any equipment or process - ESPECIALLY highly human-dependent, manual processes. Folks do like to pretend that they are infallible, or at minimum pretend that they accept culpability if Murphy strikes and their own reloads blow off their fingers, but for some reason, pretend that someone else, even someone they have trained, firsthand, is loading at substantially higher risk than their own ammo. Certainly, this isn’t the case - if two reloaders stand shoulder to shoulder over the same equipment with the same materials and follow the same processes, the same inherent risk evolves.
So if a father has any business reloading themselves, and has any business at all training other humans, then the ammunition by the trainee, the son, produced AFTER the initial training period, carries no more risk than that of the father.
