Sierra Pro-Hunter Rifle Bullets .303 cal/7mm .311" 180 gr SPT 100/ct

Sierra Pro-Hunter rifle bullets in .311" diameter and 180 grains deliver the stopping power and accuracy that reloaders demand for medium to large game hunting. Built on a traditional flat-base design proven across competitive and hunting applications, these .303 caliber/7mm bullets balance inherent accuracy with the expansion and penetration characteristics that matter when you're in the field. Whether you're hand-loading for a .303 British, 7mm Mauser, or another cartridge that chambers .311" projectiles, Pro-Hunter rounds are engineered to put game down cleanly and ethically.

The custom tapered jacket is the key to Pro-Hunter performance. That taper controls expansion rate—fast enough to deliver shock and energy transfer, but measured enough to retain bullet weight through the vitals. Deep penetration combined with reliable expansion means you're not chasing wounded animals or losing game to over-fragmentation. Sierra has built its reputation on this kind of predictable, repeatable ballistic behavior.

At 180 grains, this bullet sits in the sweet spot for medium-power rifle loads: heavy enough for authority downrange, light enough to keep velocities practical from standard hunting rifles. The flat-base design also simplifies seating consistency in the press—no fiddling with boat-tail geometry. Each box contains 100 bullets, so you can load a full season's worth of hunting rounds or test different powders and primers without breaking up packages.

If you're working up loads for a rifle chambered in a caliber that headspaces on .311" diameter bullets, Pro-Hunter ammunition components give you the accuracy and terminal performance that separates a confident shot from a frustrating miss.

Frequently Asked Questions

What calibers and rifles use .311" diameter bullets?

.311" bullets are sized for classic rifle cartridges including .303 British, 7mm Mauser, 7.65mm Argentine, and other military and hunting rounds that headspace on that diameter. Check your specific rifle's chamber specification before loading.

Are Sierra Pro-Hunter bullets suitable for hunting, or just target shooting?

Pro-Hunter bullets are explicitly designed for game hunting. The tapered jacket and deep-penetration geometry are built to expand reliably on living targets and retain weight for maximum energy transfer. They're a hunting bullet, not a target or match round.

How many reloads can I expect from one box of 100 bullets?

Each box contains 100 bullets, so you can produce 100 completed rifle rounds (assuming you have matching brass, primers, and powder). That's roughly a full season's hunting supply or a substantial test session for load development.

What's the difference between flat-base and boat-tail bullets for reloading?

Flat-base bullets are simpler to seat consistently in a press and work well for hunting applications. Boat-tail designs optimize aerodynamics for long-range precision shooting. For hunting loads, flat-base Pro-Hunters keep things straightforward while delivering the expansion and penetration you need.
