No idea how they'll work on deer just from looking at the box. Maybe they'll expand, maybe not. At least they'll punch a 0.429" hole from one side to the other.
They could be from a run of defective bullets where the inside of the jacket wasn't scored to expand. Hence the label, "For target practice".
You might want to shoot a few into whatever expansion test medium you have handy.
Good price, though. Where'd you find them?
