IBO Speed Rating Explained

Understanding the International Bowhunting Organization (IBO) speed rating is key in archery. It helps compare the speed of different bows and arrows. This metric is a standard in the industry.

Standard IBO Specifications

The IBO speed rating uses specific settings: a 30-inch draw length, 70-pound draw weight, and a 350-grain arrow. Most bows are set up to reach speeds of 300-325 feet per second (FPS).

Real-World vs IBO Ratings

In real life, arrow speeds can change a lot. This is because of things like peeps and string silencers. One archer hit 338 FPS with a special arrow and no stabilizer. Another archer shot at 308 FPS with a custom bow.

Calculating True Speed Performance

To find a bow’s true speed, archers can use known speeds and arrow weights. This gives a “corrected” IBO value. It’s more accurate than the IBO rating, which is often used.

Things like draw weight, draw length, arrow weight, and bowstring weight affect arrow speed. Practicing and aligning broadheads and field points well is key. It helps keep the arrow on track and boosts the bow’s efficiency.

Draw Length Impact on Arrow Speed

Understanding how draw length affects arrow speed is key in archery. This knowledge helps improve your bow’s performance and hunting success.

For every inch less than 30 inches, your arrow’s speed drops by 10 feet per second. If your draw length is more than 30 inches, your arrow’s speed increases by 10 feet per second for each inch.

This relationship between draw length and arrow speed is important. It lets you adjust your bow to get the best results. This is crucial for hunting effectively and ethically.

Draw Length	Speed Adjustment
Under 30 inches	Subtract 10 fps per inch
Over 30 inches	Add 10 fps per inch
