Quoted:
An acquaintance of mine was extolling me with his valuable knowledge of fire arms the other day and informed me that the .22LR is the best round for zombies, since you can carry a vast amounts of the stuff, and it can penetrate skulls quite easily.
He then proceeded to explain to me the virtues of the M14 and how it was expressly designed to fire the same round as the venerable AK model 47.
Naturally I Corrected him on the matter of the venerable M14, then informed him that I was skeptical on the matter of the lowly .22LRs skull fracturing power, and would submit the matter to arfcom for pontification.
I now await your words of wisdom about this .22 and my acquaintance, so I can due fully relay this information.
So.......let me get this straight..............
You've got this friend that has what you believe is "valuable knowledge".
This "valuable knowledge" is then applied to scenarios concerning zombies.
You overestimate the knowledge capacity of your friend.
