I just looked at this thread and see no Citrus County ranges so I will list the two I frequent.

Hernando Sportsmans Club, while not in Citrus County it's right near the county line. I'm in Citrus and can hear them shooting from the range.

And one that is in Citrus thats real nice. But a heads, up you can buy a membership for hundreds $$$. But you can also buy a $20.00 a year range card, then pay $20 for the day or a little cheaper for an hour.
They have a 600 yard rifle range but it's an extra $20 to shoot at it and you need to qualify before using it. No standing while shooting rifles is a bummer if your shooting AR type rifles, but is a nice place if your shooting long range rifles. When I want to stand to shoot, I go to Hernando even thought the place can get hectic when it's packed with shooters.
Outpost is more laid back and not hectic at all.

Anyone know if you can shoot full auto at Palm Beach county shooting sports park? It doesn’t say you can’t…

Nope
