Hey archers, if you're looking for serious performance arrows, these Gold Tip Pierce Platinums are the real deal! The .166 spine rating at 400 means these arrows are built for precision and consistency shot after shot. What's really impressive is the straightness tolerance - we're talking +/- .0025 inches, which is about as straight as arrows get. The weight tolerance is equally tight at +/- .5 grains, so you won't get any surprises when you're trying to group tight at longer distances. The 6 inch Raptor vanes provide excellent stabilization and steering without adding too much drag, giving you that perfect balance of speed and control. Gold Tip is known for their quality construction, and these Pierce Platinums live up to that reputation with durable materials that can handle regular use. Whether you're target shooting, bow hunting, or competing, these arrows deliver the consistency you need to build confidence in your shooting. The spine is stiff enough for most modern compound bows while still maintaining good flexibility for proper arrow flight. They're the kind of arrows that make you a better shooter because you can trust them to fly true every time. If you're tired of inconsistent arrows messing with your groups, these Gold Tips will quickly become your go-to choice for reliable performance.
