I would think that there is a goodly amount of info on the explosive rifle bullets. (nasty concept aint' it)
However, on "poisoned" bullets - I have never really seen much of anything that is documented. I would not think that much was ever pursued along those lines for one simple reason. Inovations like explosive or poisoned bullets would be expensive compared to lead minies and the bulk of civil war bullets never hit anything but dirt, or trees, or whatever.
And if you think about it, the chances of a lead minie causing a raging infection in a wounded man were so great, that it seems redundant to have to "poison" him as well. (I wonder if those soldiers hit in terrible climates, covered with dirt and vermin, with shards of greasy clothing blown into the wound - were suffering from almost instant infections. And that these sorts of cases led to a lot of the claims that the "yankees must be using poisoned bullets")
Doesn't seem to make a lot of sense to shoot 1000 poisoned bullets at Petersburg in the hope that one might find it's mark in a solder knowing that a lead minie would have had pretty much the same effect.
Just a thought - Gene
