For those who demand precision in their shooting endeavors, Sierra Bullets presents the .355 diameter 9mm 90-grain Jacketed Hollow Point (JHP). This ammunition is crafted for shooters who understand that every detail matters when it comes to performance and accuracy.
The ballistic coefficient of this round ranges from 0.095 to 0.115, ensuring a stable flight path with minimal air resistance. At an initial velocity of 990 feet per second, this bullet is tailored for scenarios where controlled expansion upon impact is critical—making it suitable for both self-defense and competitive settings.
Consider your environmental factors: with a wind coming from the three o’clock position at a steady ten miles per hour crosswind, you’ll appreciate how these JHP rounds handle adverse conditions without compromising trajectory integrity. The downrange component remains unaffected by wind drift due to its zero-degree elevation angle launch.
An important note on acoustics—the firing point speed of sound stands at approximately 1120 feet per second under standard atmospheric conditions (59°F at sea level). This particular bullet drops below supersonic speeds right out of the muzzle, which can be advantageous in reducing noise signature while maintaining effective terminal ballistics within typical engagement distances.
Sierra Bullets' commitment to quality ensures each round performs consistently shot after shot. When reliability meets precision engineering, you have ammunition that's ready when you are—a true companion for any marksman seeking excellence in every pull of the trigger.
