Given they claimed to be hunters, not officials, I'm fairly sure you're not right (though I'm not a US lawyer). To give a simile example to show why I think this: if someone calls me up and says "I don't like a person and wish I never had to see them again, please shoot them dead" vs. them calling me saying "I don't like a person and wish I never had to see them again" and me thinking on my own and shooting them dead - either way, I'm choosing to do something illegal, and I haven't been asked to do it by anyone I have reason to believe has the authority to let me legally murder someone. My shooting the person would, rightly, be illegal and not entrapment even if the person pretending to be my friend on the phone actually was a police officer.
