I love both rounds, but if that is all you are doing stick with the .243 cheaper, plenty effective, and in florida I doubt you will need the range of a .270. I got a 30-06, .270, and .243. I've killed the most with the .243. Even though I did just get the 30-06, and it will be the most used next season. I've never had a deer go past 20 feet after being shot with the .243, the thing was damn accurate.
