Traveling to FL from OH to hunt. Mail my gear, or bring in checked luggage?

UPS or USPS for sure.

Send them air freight from the airport. They arrive at your destination airport cheap. They don't deliver. You must drop off and pick up from the air freight terminal at the airport. Not the passenger terminal. They will get there before you do.
This is excellent does every airline do this I need to look into this how come more people are not doing this.

I don't know. But every major airport has an air freight area with many carriers.

I shipped mine American Air Freight a couple times. Oakland to El Paso and SeaTac to El Paso. The rifles got to El Paso before I did both times.

There are lots of Air freight outfits going between airports. If you shop around you will find a carrier.
