How to Tune a 300+ FPS Bow for Perfect Accuracy (Step-by-Step Guide)

Unlocking the full potential of a 300+ FPS compound bow requires precise tuning—especially when pushing speed limits without sacrificing accuracy. Whether you’re prepping for elk season or 3D tournaments, these tuning high-speed compound bow tips will transform your setup into a precision machine.

Step 1: Match Arrow Spine to Bow Speed

High-FPS bows demand stiffer arrows. For 300+ FPS setups:

• 350–400 spine arrows (e.g., Easton Axis 5mm) for 60–70 lb draw weights.
• 100-grain points to maintain stability (lighter points can cause fishtailing).
• Test: Shoot through paper at 10 yards—clean tears mean proper spine alignment.

Step 2: Synchronize Cams for Perfect Timing

Out-of-sync cams cause erratic arrow flight. Use these tuning high-speed compound bow tips:

1. Draw and hold at full tension: Check if cams roll over simultaneously.
2. Adjust yoke cables (1/4 turn at a time) until cams move in unison.
3. Verify with a bow press if needed (Hoyt/Bowtech models often need professional tools).

Step 3: Paper Tune for Bulletproof Flight

• Hang paper 6 feet from bow.
• Shoot arrows at 10 yards.
  • Tear left/right? Adjust rest lateral position.
  • Tear high/low? Modify nock point height.

Step 4: Broadhead Tuning (Critical for Hunting)

Field points and broadheads must hit the same mark:

1. Start with mechanical broadheads (more forgiving at high speeds).
2. Test at 40 yards: Adjust rest until groups match field points.
3. For fixed blades: Use broadhead-specific arrow spines (stiffer for better penetration).

Pro Tip: Reduce Vibration for Consistency

• Install string stops (like Limbsaver S-Coil).
• Use heavier stabilizers (8oz+) to dampen shot shock.

For 300+ FPS bows, micro-adjustments matter. If arrows still fishtail after paper tuning, try 1/64″ rest adjustments or switch to carbon arrows with tighter tolerances (e.g., Victory VAP Elite).

EliteArcher’s tuning kits include cam timing gauges and paper tuning frames—essential for DIYers. Remember: Even the fastest bows miss if out of tune. Schedule a professional tune-up before opening day.
