I would go with either the American Hunter or Field & Stream. As Oldtimr mentioned, those are 2 of the 3 biggest selling magazines that are subscribed to, as well as more probably being purchased off store shelves by other people. I would not think that your money would be well spent by advertising in the American Rifleman that he mentioned because it's more about people that are into guns than hunting. Just be aware that to advertise in one of those magazines will cost you a lot of money. You may be a lot better off advertising on a hunting website like this one where you can be seen by a lot of people for free. I'm going to send you a PM (Private Message) with a website that you should be on that has a lot of rich people from all over the world on it and you can advertise for free on it. I can't say the name out on here because it's against the rules here. Look for a message at the top right of this website that I'm going to send you.
