If you're looking for long range like 1k plus, it's pretty limited.
Depending on which area of Tampa you're in, travel times can vary quite a bit.
Otherwise, as mentioned you have Manatee which is an hour and fifteen minutes south of Tampa area. It got very Fuddish because of the ROs, and I haven't been there in years.
Shoot Straight in various locations has 100yd indoors.
Shooter's World, one location has 100 indoors.
Fishawk Sporting Clays has a 100 yd rifle range, plus pistol and SC.
Shoot Shack is south of Lithia on Hwy 39.
Privately owned and limited to just under 300 yards.
The 300 is available if the cows aren't invading the range...
Haven't been there since JTAC opened.
Saddle Creek on the east side of Lakeland. 100yds.
Tenoroc is between Lakeland and Mouse country. It's limited to 100yds unless they made changes since the last time I went there.
Ares Training Facility near Whorelando is private and from what I'm told only members can shoot long range.
Tradecraft is over two hours south. 2 miles available.
JTAC is 40 minutes or less. You must be with a member that has access to long range areas, but that's the only real restriction. 2k available.
Going west, you have Wyoming Antelope Club which is limited to 200 IIRC.
Going further west you need a boat...
If you want to dig in, use Google search and type in "shooting ranges in Florida".
I tried to link it for you, but the copied link included a bunch of unnecessary text.
