Don't forget all the duck stamps and hunting/fishin license fees and the taxes on hunting gear that go towards state and federal conservation and wildlife management programs.
Yes, the Pittman-Robertson Act has provided untold money for wildlife over the years. During HS I worked in a sporting goods store and remember when the price of Duck Stamps increased from two to three dollars, a few customers thought that was outrageous. LOL! I have no idea the cost of one now.
