Long term SHTF ammo and TKO Qn

[Puncha]

Firstly, what do you guys have to say about using the Taylor Knockout Formula (TKO) as a means of guaging the effectiveness of low velocity handgun ammo?

I'm talking about situations where you have your sidearm and enough ammo to take multiple shots in defense of life and limb.

Secondly, if you were going to keep a few 50rd boxes of .38 special/9mm or similar medium bore ammo in your BOB, would you choose

I) Freshly manufactured +P LRN/FMJs with heavier projectiles (158gr/147gr) and good TKO and momentum values?
Or
II) 10 year old non +P HP ammo with lighter projectiles (110gr/115gr) and poorer TKO and momentum values?

Lately, I've been thinking that if overpenetration was not an issue, pure knockdown power and the economy of high quality fresh and reliable old fashioned LRN/FMJ loads seem logical than older ammo (that may not have been previously stored right), may not expand as advertised, may not penetrate as required and may have velocity issues due to powder degredation.

Ps: Am not trying to start a light/fast vs slow/heavy flame war!

It is not how....

big or powerful the cartridge is, but, where you place the bullet...........everything else is a topic for gun forums........chris3

Basically....

....it has to go bang without fail 100% of the time. Next, it MUST penetrate through at least a leather jacket and T-shirt and dig through 10-11"s of flesh. Lastly, you HAVE TO BE accurate with the choosen load at ranges up to 15 yards under stress. Quality LRNs loaded warmly will fill this need.

YMMV

Basically, if I were planning to stockpile ammo today with a view towards some emergency that might not happen for ten years, I would not be inclined to lay in ammunition that is already ten years old.

Keep it dry and any decent factory loads will last for decades sitting on the shelf. I've personally fired hundreds of rounds, centerfire and rimfire, that were over 30 years old by the time i used them. Not one of them failed to go bang. I can't vouch for imported ammo, the loads i used were all federal, remington or winchester - ( which is basically all there was around when i was a kid and bought the stuff in the early 70's ) but based on my experience with that, i'd say any decent factory ammo would have as good a chance of lasting that long or longer.
