I am Robert Gilbert, USA Archery Level 3 NTS certified coach and owner of Archery Sarasota. Every season I work with Florida bowhunters who are running setups optimized for speed and light arrows. They show me tight groups at 30 yards on a calm range. Then they ask why they lost the hog or had a poor exit hole on their deer.
The answer is almost always the same. Speed is visible. Momentum is not. The physics that actually kill Florida game are happening at the target, not on the chronograph screen. This post covers what you need to know to build a setup that is both accurate and lethal on the animals you will actually encounter in this state.
The short answer: match your draw weight to a poundage you can shoot with full accuracy and hold steady under pressure. Then build arrow weight and FOC to maximize momentum and penetration for your target species. Shootable accuracy beats maximum poundage every single time.
Always check current Florida Fish and Wildlife Conservation Commission (FWC) regulations for any legal requirements before the season. This post focuses on what is effective, not on quoting regulatory numbers that can change.
Why Florida Game Punishes Light-Arrow Setups
Florida presents three main bowhunting targets: wild hogs, whitetail deer, and osceola turkey. Each has different anatomy, and hogs in particular reward setups that most compound archers in this state are not running.
Wild hogs have a cartilage plate called the shoulder shield. It sits just behind the front leg and directly over the vitals on a quartering-to or slightly quartering-away shot. This plate is dense, tough, and specifically evolved to absorb blunt trauma from other hogs. It resists fast, light arrows far better than it resists slow, heavy ones. This is not an opinion; it follows directly from the physics of momentum.
Momentum is mass times velocity. A 350-grain arrow at 290 fps carries a specific momentum value. A 550-grain arrow at 265 fps carries more of it, despite being slower. More momentum means the arrow pushes harder through resistance. When that resistance is a hog's shoulder shield, the heavier arrow wins. Speed matters much less than mass at the point of impact.
Florida whitetail are smaller than northern deer. A mature buck here rarely tops 130 pounds. They do not require the same penetration as an elk or a mule deer. But they still reward clean double-lung hits, and that requires a sharp broadhead that enters and exits on a tight trajectory. A light arrow deflected by a rib or a branch creates a marginal hit. A heavier arrow with more inertia holds its line better on contact.
Turkey are a different challenge. The vital zone on a turkey is small. Shot placement is the dominant factor. Your arrow setup matters less here than with hogs, but a heavy cut-on-contact broadhead through the spine at 20 yards is instant. A mechanical at the same distance on a tough tom can produce a runner.
Draw Weight. What You Can Shoot Beats What You Can Pull
There is a common belief in bowhunting culture that more draw weight equals more killing power. To a point, that is true. But the ceiling is reached much sooner than most hunters think, and the cost of exceeding it is accuracy.
A hunter shooting 60 lbs with a relaxed, consistent form will outperform a hunter shooting 70 lbs with a flinch, a rushed draw, or a shortened follow-through. Every time. The second archer is not getting more penetration from that extra 10 lbs. They are getting a slightly faster arrow from a degraded shot. Degraded shots wound animals.
Here is what I tell every new hunting client: find the heaviest draw weight you can hold at full draw for 30 seconds in a field shooting position without your form starting to break down. That is your working weight. Not your maximum. Not what the bow was set to when you bought it.
For smaller-framed archers and younger hunters, this often means shooting in the 45 to 55 lb range. That is enough poundage to kill every Florida game animal cleanly when the right arrow is behind it. A 45 lb bow pushing a 500-grain arrow with a sharp 100-grain fixed-blade broadhead has more momentum than a 70 lb bow shooting a 350-grain arrow at 295 fps. Check the math. The physics back the heavier arrow.
If you want help dialing in the right draw weight for your frame and your target species, that is exactly what we cover in bowhunting coaching here at the shop.
Arrow Weight and the Momentum Calculation
Arrow weight for hunting is measured in grains. One grain equals 0.0648 grams. A field target or 3D arrow might run 300 to 380 grains. A hunting arrow built for momentum typically runs 400 to 600 grains or more.
The momentum formula is straightforward: (arrow weight in grains divided by 225,400) times velocity in fps equals momentum in slug-feet per second. You do not need to run this math by hand. What you need to understand is the direction of the relationship. Adding weight to your arrow increases momentum. Reducing weight to gain speed reduces momentum more than it helps at hunting distances.
A useful field rule: at shot distances under 40 yards, adding 50 grains to your arrow weight costs you roughly 3 to 5 fps of speed and gains you a measurable increase in penetration force. That trade is worth it on hogs and is neutral on whitetail. It only hurts you if you are regularly taking shots past 50 yards where flat trajectory matters.
For Florida hunting, build your hunting arrow in the 450 to 550 grain range if your draw weight supports it. Broadhead included. If your draw weight is lower, a 400 to 450 grain arrow is still hunting-capable with the right broadhead choice.
Arrow Spine. Why a Mismatched Spine Undoes Everything Else
Spine is how much an arrow bends under the force of the shot. Every arrow shaft is rated by its spine deflection. A stiffer spine bends less. A weaker spine bends more.
If your spine does not match your draw weight, point weight, and arrow length, the arrow leaves the bow in an inconsistent flight path. You can have the right weight, the right broadhead, and a well-tuned bow and still get inconsistent groups because the spine is wrong. Broadheads make spine mismatch much more visible. An arrow with a fixed-blade broadhead acts like a vane in the wind. If the spine is weak, the broadhead turns the arrow into a weather vane and groups open up dramatically beyond 20 yards.
Spine selection charts from manufacturers like Easton and Gold Tip give you a starting point. Actual tuning confirms it. The paper tune or walk-back tune at distance tells you whether your spine is right for your setup. This is not a step to skip if you are building a new hunting arrow.
When you add weight to reach your target arrow grain total, you add it at the front (heavier insert, heavier broadhead) or at the rear (heavier nock, brass nock insert). Weight added to the front weakens effective spine. Weight at the rear stiffens it. A good arrow build accounts for this and spine-selects accordingly. Our bow tuning service includes arrow matching so your spine selection is verified, not guessed.
FOC. Where the Weight Sits on Your Arrow
Front of center (FOC) is the percentage of total arrow weight that sits in the front half of the shaft. Higher FOC stabilizes the arrow in flight, especially at hunting distances, and improves penetration on impact because the arrow wants to drive forward rather than oscillate or deflect.
For most hunting setups, FOC in the 10 to 15 percent range is a solid target. You can push into 15 to 20 percent for hog-specific setups and see real gains in penetration through the shoulder shield. Going past 20 percent starts to hurt long-range accuracy for most shooters, so there is a practical upper limit unless you are a dedicated traditional archer running heavy, short shots.
You increase FOC by using a heavier broadhead, a heavier insert, or both. Moving from a 100-grain broadhead to a 125-grain or 150-grain broadhead is the simplest lever. Heavy inserts (50 to 100 grains) let you keep your broadhead weight moderate while still shifting the balance point forward.
The formula: measure the overall length of the arrow from the groove in the nock to the tip of the broadhead. Divide that in half to find the midpoint. Then find the actual balance point by resting the arrow on your finger. Measure how far the balance point is ahead of the midpoint. Divide that distance by the overall length and multiply by 100. That is your FOC percentage.
A quick check: for hog hunting in Florida, run at least 12 to 15 percent FOC with a cut-on-contact fixed-blade broadhead. For whitetail, 10 to 12 percent is fine. For turkey, point and shoot placement matter more than FOC specifics.
Speed vs Penetration. The Tradeoff Florida Hunters Need to Understand
Fast arrows are popular because speed is easy to measure and impressive to watch. A 300 fps arrow looks great on a chronograph. It hits flat and forgives ranging error at longer distances. Those are real advantages for target archery and for open-country western hunting where 60-yard shots are common.
In Florida, most shots happen under 35 yards. Dense palmettos, cypress stands, and swamp edges close the distances fast. Your arrow will not be in flight long enough for trajectory to be the primary variable. What matters at 25 yards is whether the arrow penetrates clean through both lungs or clips something and deflects.
At short distances, penetration is driven by momentum and broadhead sharpness. A slow, heavy arrow with a razor-sharp cut-on-contact broadhead will out-penetrate a fast, light arrow with a mechanical at every Florida shot distance you are likely to take. This is not a controversial claim. It is what the physics say.
The tradeoff is trajectory. A 550-grain arrow at 255 fps drops noticeably more than a 350-grain arrow at 295 fps between 30 and 50 yards. If you are disciplined about shot distance and range your shots before drawing, this does not cost you anything. If you are guessing distances at dusk, a lighter, faster arrow is more forgiving. Know which hunter you are before you build the setup.

Sensible Setups by Game and Archer Type
Here is how I think about Florida hunting setups by target species and archer build.
Wild hogs, average-to-large-framed adult archer (55 to 70 lbs draw): Arrow in the 500 to 600 grain range. FOC 13 to 18 percent. Fixed-blade cut-on-contact broadhead, 100 to 125 grains. Spine matched to your draw weight and point weight. Speed will likely land in the 260 to 285 fps range. Momentum is excellent. Shot placement: behind the front leg, through both lungs, quartering-away preferred.
Wild hogs, smaller-framed archer or younger hunter (40 to 55 lbs draw): Arrow in the 450 to 520 grain range. FOC 12 to 16 percent. Same cut-on-contact fixed-blade recommendation. Speed around 240 to 265 fps. Momentum is adequate for clean kills at ethical distances (under 30 yards is smart for hogs at this weight). Avoid shoulder shots entirely. Wait for a clean quartering-away angle.
Florida whitetail, any draw weight: Arrow in the 400 to 500 grain range. FOC 10 to 14 percent. Fixed-blade or high-quality mechanical both work. Whitetail are forgiving of setup variables when shot placement is right. Focus on a broadhead you can tune to group with field points, then let shot placement carry the rest.
Osceola turkey: Arrow in the 350 to 450 grain range is fine. FOC matters less here. Use a guillotine-style or large mechanical specifically designed for turkey. Aim for the spine just below the head for an instant kill, or the body fold at the wing base if you are taking a body shot. Turkey have small vitals. Any setup works if you hit the right spot.
Across all of these, the common thread is this: shoot the draw weight you can hold and aim with clean form. Build arrow weight and FOC to match your poundage and your target animal. Verify your spine. Use a sharp broadhead you have tested against your field points at range. That combination, not maximum poundage, is what kills cleanly.
