I have participated in discussions on this subject, on other forums, and I always end up getting swarmed by the folks who adamantly oppose the idea of carrying hand loaded self-defense ammo. I understand that this is due mainly to the fact that all of the self-defense writers strongly recommend the use of factory loaded ammo, and many even recommend using exactly the same ammo as local law enforcement.
I completely understand the arguments about how a lawyer might be able to influence a jury, by suggesting that custom-made 'killer' bullets were used to insure maximum damage. I understand that the consensus is that it is just best not to add another possible variable into an equation that could possibly result in your conviction, or an unfavorable civil judgment...or in larger defense fees being incurred to counter such arguments with expert witnesses, etc.
Personally, I am dead in the middle, on this issue. I understand the common sense argument, yet I also understand that it is an argument that is really not backed by much actual evidence. There are very few cases that can be cited in which hand loaded ammo was even mentioned, and even fewer cases where the use of hand loads were a factor in deciding the case. I have only ever seen two mentioned, personally, and in both cases, hand loads were peripheral to the main issue. I still carry factory loaded ammo, but should my preferred ammo become unavailable, I would not hesitate to carry my own hand loaded ammo. I am mostly unconvinced that this would be a disaster, should I ever have to fire my weapon in self-defense.
I'm not a lawyer, and I don't have any special ability to look for such cases, but common sense tells me that if they existed, I would be able to find more references to them, on the Internet. If anyone can cite instances where hand loaded ammo played a part in the conviction of a person who was defending himself, I would like to read them, and I would like to see more opinions on this subject.
