The Hornady Subsonic Rifle Ammo 45-70 Gov 410 gr Sub-X is a go-to load for hunters and shooters who need heavy-for-caliber momentum with reduced report and low flash, offering 1075 fps and about 1052 ft-lbs of muzzle energy for deep, controlled penetration in brush and wooded environments. This Subsonic series round pairs the proven Sub-X bullet profile with a brass casing and reliable primers to deliver consistent accuracy from lever-action and single-shot rifles, and its reduced velocity makes it well suited for use with a suppressor when quieter performance is desired. As part of Hornadys Subsonic lineup, this cartridge retains terminal effectiveness at typical hunting ranges while minimizing over-penetration and recoil, which makes follow-up shots faster and less disruptive on the range or in the field. Hunters pursuing deer-sized game in heavy cover will appreciate the weight and sectional density of the 410-grain Sub-X bullet, and precision-minded shooters will find the rounds stable flight and low muzzle signature beneficial for stalking, close- to mid-range work, and range training with reduced noise. Made in the United States and optimized for subsonic applications, this Hornady round balances power and sound suppression readiness for serious users.
