I believe you have some options for bullets cast in Florida, if you don't want to pay shipping...
There are these guys in Melbourne, and I've shot some of their bullets, which have been very accurate:
<style> </style> SPACE COAST BULLETS
Here's another company I found by searching the net in Valrico FL, and you may want to give them a call...
Bullseye Bullets
1610 S.R. 60, #12
Valrico, FL 33594
(800) 741-6343
There is a good chance that either one of these company deliver close to you, or might exhibit at a gunshow near you so you could pick them up there without paying shipping.
Another great one to try if you want to order some in is
Tennessee Valley Bullets - Jessie makes some darn great stuff- soft or hard, as you want it if you order enough of it.
I mostly shoot low velocity target stuff, and rarely if ever push anything very hard- so finding casters that cast it soft enough for my needs is paramount- many cast very hard for guys that want to push it hard, even wadcutters.
