When I hunted in Southwest and South Central Florida for two decades I used a ruger tanger wood stock blued 30-06. Weather could be wet and humid but mostly my concern was my sweaty hands. I used a dish rag and rem oil on the rifle at the end of everyday. Never any rust or any issues with it. I was out in the woods from 3-5 day stretches.
Alabama is where I hunt now and it is wet there in the hunting season. I use synthetic and stainless or coated rifles there these days. I wipe them dry with a cloth every day and clean and wipe them with CLP.
