Subsonic shooting has never been more capable than with the Hornady 30 CAL .308 190 GR SUB-X Projectile - 100pk. Built around Hornady's patented Flex Tip® technology, these projectiles are engineered to expand reliably at velocities as low as 900 fps (274 m/s), making them purpose-built for suppressed hunting and pest control applications where keeping noise to a minimum is a priority. The 190 grain bullet weight and .308" (7.82mm) diameter are optimised for stabilisation through rifling with a 1:10 twist or faster, and the G1 ballistic coefficient of 0.437 helps maintain trajectory consistency even at the reduced velocities inherent to subsonic loads. With a pack of 100 projectiles, this is a serious reloading option for hunters and sport shooters who want to build dependable subsonic ammunition.

Hornady 30 CAL .308 190 GR SUB-X Projectile - 100pk Key Features

  • Flex Tip® Technology: Hornady's patented Flex Tip® insert sits within the hollowpoint cavity and initiates reliable expansion at velocities as low as 900 fps (274 m/s), where traditional hollowpoints often fail to open consistently.
  • Subsonic Expansion Design: Long grooves in the gilding metal jacket, combined with the flat profile and Flex Tip® insert, work together to drive consistent expansion below the speed of sound, ensuring reliable terminal performance in suppressed rifle setups.
  • Lead Core Construction: A lead core delivers the mass and density needed to maintain momentum and achieve deep penetration at reduced velocities, which is critical when hunting medium game.
  • Bullet Weight and Diameter: At 190 gr and .308" (7.82mm), this projectile is a proven combination for subsonic .30 calibre loads, providing the sectional density needed for adequate penetration on medium game up to 300 lbs (approx. 136 kg).
  • G1 Ballistic Coefficient (0.437): A BC of 0.437 is strong for a subsonic-oriented projectile, helping to retain velocity and limit wind drift at the ranges where subsonic loads are typically employed.
  • Cannelures for Positive Case Crimp: Machined cannelures allow reloaders to apply a firm, consistent crimp, which is particularly important for reliable feeding and function in semi-automatic gas-operated firearms.
  • Fits, Feeds and Functions: Designed to cycle reliably across a range of rifle platforms including gas system guns, reducing concerns about feeding reliability when building subsonic loads for semi-automatic rifles.
  • Meets FBI Terminal Ballistic Protocols: These projectiles meet FBI protocol terminal ballistic test requirements, confirming that expansion and penetration performance has been independently validated to recognised standards.
  • Twist Rate Recommendation: Optimised for barrels with a 1:10" (1:254mm) twist rate or faster, which aligns with most modern .30 calibre rifle barrels and ensures adequate gyroscopic stability at subsonic speeds.
  • Pack Quantity: Supplied in a 100-projectile pack, offering strong value for reloaders developing and shooting subsonic loads in volume.

For hunters and sport shooters investing in suppressed .30 calibre setups, the Hornady SUB-X projectile takes the guesswork out of subsonic terminal performance. These are purpose-engineered components that bridge the gap between reduced-noise shooting and genuine on-target effectiveness, making them a standout choice for anyone reloading for suppressed hunting use or quiet range sessions.

What makes the Sub-X bullet expand reliably at subsonic velocities?

Hornady's patented Flex Tip® technology enables reliable expansion at velocities as low as 900 fps. Long grooves in the gilding metal jacket, combined with a flat profile and the Flex Tip® insert within the hollowpoint cavity, work together to initiate and sustain expansion even when the bullet is travelling below the speed of sound.

Is this projectile suitable for use in semiautomatic and gas-operated rifles?

Yes, the Sub-X is designed to fit, feed, and function in a variety of firearms including gas system guns. Cannelures around the bullet provide a positive case crimp, which helps ensure reliable cycling in semiautomatic platforms — an important consideration when loading subsonic ammunition.

What twist rate does my rifle barrel need for these projectiles?

Hornady recommends a barrel twist rate of 1:10 or faster to stabilise the 190 gr Sub-X projectile. Given its length and weight, slower twist rates may not provide adequate stability for consistent accuracy at subsonic velocities, so check your rifle's specifications before reloading.

What size game are these projectiles recommended for?

The Sub-X 190 gr is recommended for medium game up to 300 pounds. Designed for deep penetration at subsonic speeds and meeting FBI protocol for terminal ballistic performance, it's a purposeful choice for hunters or shooters requiring effective terminal results with reduced sound signature.
