Overview
Designed for varmint and small-game applications, this bullet is intended for shooters who want a fast-expanding option with accuracy associated with Sierra’s MatchKing line. Its proprietary tip and thin jacket are part of the design for explosive expansion and precise shot placement. In 20 caliber, it is among the lighter bullets intended for use at muzzle velocities up to 4400 fps, making it a fit for high-velocity loads where that performance window is appropriate. Always confirm load data through your reloading manual or the powder manufacturer’s website before use.

- The emphasis on explosive expansion and thin jackets may be a trade-off if you want a bullet with a more controlled terminal effect.
- Load development is still required; Sierra directs users to consult a reloading manual or powder manufacturer data before use.
- The stated high-velocity guidance applies to lighter bullets in specific calibers, so this product should be matched carefully to the intended cartridge and load.
