All the case facts and links in the world will not matter one iota if your rear is sprawled out on the ground with a smoking hole in your chest.
Like I mentioned back somewhere on another page, before this went into more or less a discussion only topped by religion, I'm going to use whatever is loaded at the time as will anyone else here. No one can predetermine when, or where, or any other circumstance, when a BG decides to do a dirty deed.
Case in point,
I was sitting at a stop sign on a busy city street when a fellow walking across the cross walk eased right up to my driver side window and stuck a revolver in my face. Not much to do in that situation but give him what he wants and hope for the best. No concealed handgun would have changed anything about it. Even if I would have had one, I would not have been able to use it until he backed away, at which time he high tailed it away through the traffic. No way to shoot him other than in the back and that would not be self defense but murder, or in the very least manslaughter.
In that time frame, again, they aren't going to wait for you, me, or anyone else to remove handloads and replace them with factory ammo. Right, wrong, or indifferent, if my or my family's life is at stake, or anyone else who has posted to this thread for that matter, unless you simply give up hope and leave your fate in the hands of who knows what, your going to shoot first and then hope and pray for the best, factory ammo or not.
I do not have but a few boxes of factory ammo period, never have and never will. What I DO have is mostly for my deer rifles. Like I mentioned I handload, mostly for everything, always have and probably always will. It will be pretty easy to determine how any of my loads shoot as I pick one load and stick with it. Just pick the box for the caliber I used and there ya have it. I hope and pray I am never forced into the circumstance where I have to use deadly force, but if so, I'll use whatever I have to defend myself, as will just about anyone else.
Oh yea, I forgot, that is a YES from me.
