SIE 9mm 147GR JHP V-Crown Ammunition - 100 Rounds/Box

The Sierra Bullets 9mm 147-grain JHP V-Crown ammunition is a heavy-for-caliber defensive round engineered for controlled expansion and reliable performance across the full range of 9mm velocities. Developed in partnership with Sig Sauer, this round combines Sierra's precision bullet design with a stacked hollow-point cavity and locking groove that work together to manage expansion while preserving weight retention—critical factors for consistent terminal performance in defensive encounters and duty use.

The 147-grain bullet weight makes this round particularly well-suited to subsonic applications, especially from 9mm carbines and short-barrel rifles where maintaining velocity below the sound barrier is a priority. Whether you're running a 9mm SBR, an integrally suppressed platform, or simply prefer heavier 9mm loads for reduced recoil and softer handling, Sierra's V-Crown design delivers the accuracy standards Sierra is known for without compromising expansion reliability.

This is a reloading component—individual bullets packaged 100 per box—allowing handloaders to assemble custom ammunition tailored to their specific firearm, velocity requirements, and performance goals. Sierra's sectional density of .167 and published ballistic coefficients (.162 at velocities 1200 fps and above, .220 between 1200–930 fps, and .165 below 930 fps) give reloaders the data needed for precise load development and trajectory prediction.

Frequently Asked Questions

What's the purpose of the stacked hollow-point cavity and locking groove?

The dual hollow-point design and locking groove work together to ensure reliable expansion across a wide velocity range while maintaining high weight retention. This is especially important in defensive ammunition, where consistency matters. The groove also helps control how quickly the bullet opens, preventing over-expansion and ensuring adequate penetration.

Are these bullets suitable for subsonic 9mm loads?

Yes. The 147-grain weight is specifically chosen to support subsonic velocities in 9mm cartridges, making these bullets ideal for subsonic loads, suppressed firearms, and short-barrel rifles where keeping rounds below the sound barrier is desired.

Is this finished ammunition or a reloading component?

These are reloading components—individual bullets only, not loaded rounds. You'll need to pair them with 9mm brass, primers, and powder to assemble complete ammunition. Each box contains 100 bullets.

What ballistic coefficient should I use for load development?

Sierra publishes three ballistic coefficients depending on velocity: .162 for 1200 fps and above, .220 between 1200–930 fps, and .165 below 930 fps. Use the coefficient that matches your expected velocity range for the most accurate trajectory and external ballistic calculations.
