For the most part, waterfowl and upland bird conservation groups leave defending the Second Amendment to the National Rifle Association. There are a variety of reasons they do so, but these are no longer ordinary times for gun rights.
I’m just guessing, mind you, but I believe the first American deer rifle was the Model 94 Winchester. To be sure, a lot of deer fell to Model 73s, Marlins, Trapdoor Springfields and flintlocks, but the first sporting deer rifle was the 94. Since that iconic rifle there have been a whole lot more.
