I am so paranoid I only let myself and immediate family shoot my reloads and only when I am standing right beside them when they shoot. Only had 1 squib in 4 years of reloading but it can happen to the anyone.
Side note is that factory ammo can also cause squibs. I have been shooting off and on over 50 years now and witnessed it happen for the first time last weekend with a factory 9mm during a competition.
