HRNDY 30-30 WIN 175GR SUB-X 20/200

Description

Hornady’s Subsonic line in .30-30 Winchester is built around a single practical goal: reliable terminal performance at velocities that stay below the sound barrier. That matters because standard expanding bullets are engineered to open at centerfire rifle speeds — push one too slowly and you get inconsistent or failed expansion. The Sub-X bullet solves that by combining a lead core with a gilding metal jacket cut with long external grooves that weaken the structure in a controlled way, so the jacket peels back predictably even when velocity is low. The hollowpoint cavity is fitted with Hornady’s Flex Tip insert, a polymer plug that resists deformation during feeding and transmits hydraulic pressure into the cavity on impact to initiate expansion. Without it, a hollowpoint running at subsonic speeds risks collapsing inward or plugging rather than opening.

At 175 grains, this is a meaningfully heavier projectile than most .30-30 hunting loads, which typically run between 150 and 170 grains. The added mass helps carry energy downrange despite the reduced muzzle velocity of 1,050 feet per second, producing 428 foot-pounds at the muzzle. That trade-off — more weight for retained energy at low speed — is the design logic that makes the round viable for medium game rather than merely a range curiosity. The brass cases are reloadable and use Boxer primers, which is practical if you plan to work up handloads around suppressed use. Powders are selected for consistency across production lots, which is relevant when you are timing a gas-operated action or tuning a suppressor’s back-pressure behavior. Sold in 20-round boxes.
