Quick Answer
YOUR BOW MAY BE SHOOTING LEFT DUE TO A VARIETY OF REASONS, INCLUDING INCORRECT CAM TIMING, IMPROPER ARROW REST ADJUSTMENT, OR A BOW THAT IS NOT TUNED TO THE PAPER TUNING POINT.
Common Causes of Left-Shooting Bow
When your bow is shooting left, it’s essential to identify the root cause. Incorrect cam timing is a common issue, which can be caused by improper stringing or a worn-out bow. Cam timing is critical, as it affects the bow’s draw cycle and arrow flight. Ensure that your cam timing is set according to the manufacturer’s specifications, typically between 26-28 inches (66-71 cm) of string movement at the 80% draw weight.
Troubleshooting Techniques
To troubleshoot your left-shooting bow, try walk-back tuning. This involves setting the arrow rest to a position where the arrow is 1/4 inch (6 mm) away from the bow’s nocking point at the 80% draw weight. Then, walk the rest back 1/4 inch (6 mm) at a time, checking the arrow’s flight and making adjustments as necessary. Another technique is paper tuning, where you use a paper target to determine the bow’s accuracy and make adjustments to the cam timing and arrow rest accordingly.
Arrow Rest Adjustment and Cam Timing
To adjust the arrow rest, loosen the rest’s screws and move it towards or away from the bow’s nocking point. Make small adjustments, checking the arrow’s flight after each change. When adjusting the cam timing, use a bow press to ensure the bow’s limbs are securely held in place. Loosen the cam’s screws and adjust the timing according to the manufacturer’s specifications or the results of your paper tuning. It’s crucial to make small adjustments, retesting the bow’s accuracy after each change, to avoid over-correcting and causing further issues.
