I keep a 30-30 in My truck as my primary SD weapon. My Pistol is just to fight my way to the rifle. I thought the 30-30 with its friendly wood stock and cowboy looks would be less threatening than my M4. Its good to know that if I shot a drunk he will be DRT and not spill any beer
I am not so sure their this data is true. Its hard to believe that many folks have been killed with PMC ammo. Look at the 38spl data. If its to be believed the 38spl in a 2" gun is more deadly that in a 4".
M&S have been compiling this data for a long time but I am leery of some of it. I checked out the "Best Self Defense ammo" article and the data is almost wholly based on testing.
There are some good points to these tests though:
1. Have a Gun
2. A man with a rifle will kill a man with a pistol, right Blondie
3. Bullet placement is king and Penetration is queen.
Lastly I did not see any shotgun data, maybe I missed it but a shotgun would be my second choice after a rifle for SD(Notice I did not say CCW)
