Is there a good document on the M855A1 stuff?
Kevin pointed out the following:
1st tin/bismuth base, steel tip, copper jacket
2nd copper base/jacket, steel tip
3rd solid steel 1pc core, copper jacket (is there a way to ID this? Magnet I guess?)
"Early Experimental tin/ bismuth core, copper core, Solid Steel core (Looking for info), and several malfunctions. "
