i found these WW2 50 cal bullets. The blue tipped one is an incidiary bullet, but I am looking for advice as to how dangerous these are for having around. Many thanks in advance.
The blue tips are safe to a point.... No problem when beeing careful. I wouldn't keep these and the "rare" silver tips.
You can carefully cut the bullet at the tip with a saw blade, break open and strew the filling in a paper towel slice. Only a bit!!! Then wrap the paper close, put on a stone outside far from any flammable stuff and ignite the paper far from the filling and step away. Make sure to wear sunglasses! I will be a nice flash!
Don't tell anyone this is coming from me.... I tell you: Don't do that!
