I use to use a 30-06 Springfield rifle A bad ass gun even at a 100 yards. I almost went to jail 2 yrs ago for using an AR15, it fires a 223, I liked that because of the semi auto.
Last year I switched up, Now I use a bad ass compound bow, it took me six fucking months to get the hang of it, and at a 100 yards it is fucking awesome. I am not sure beyond that distance. It took sometime to get use to pulling it back, even being a compound bow. Pulling 70lbs is not an easy task. The downside is it is 500 bucks, the cost of my Baby Desert Eagle.
I had one doe last year, this coming season, with all the practice I am getting in, I hope for two this yr.
I have not tried gator hunting as of yet, that is on my bucket list of things to do. My fuck it list is a lot longer..
