So my grandfather passed recently and was an avid gun owner, shooter and reloader, having done all three for decades. When I shot with him years ago it was his reloaded ammo. Now I'm looking at possessing supposedly 1000+ rds of 5.56, some for a very old lever action and who knows what else. Problem is the reloads are newer, and there's no telling how "there" he was mentally. I believe he shot fairly recently with others and no blown off hands. Do I trust the old man's work? Visual inspection and weighing the rounds good enough?
