I'd focus on preventing a bite rather than addressing an envenomation. This summer, on two occasions, I almost stepped on a Timber Rattler. Both very large. It changed, forever, what I will wear in certain areas.
I would recommend getting snake gaiters, particularly Turtleskins. They are lightweight and feel like nornal gaiters. Also, make sure you wear a leather boot that will not allow a snake's bite to penetrate. With those two, you sure be able to hunt safely.

I also bought the Turtleskin chaps which will protect me to the top of the leg. I got those because I'm often bushwhacking in areas where the underbrush makes it impossible to see what I'm stepping on. The chaps allow me to walk with ease and not have to concentrate, or be concerned, where I step.
