HSM 7STW8N Game King Hunting 7mm STW 160 gr Sierra GameKing Spitzer Boat-Tail (SGSBT) 20 Per Box/ 20 Cs

The HSM Game King 7mm STW 160 gr Sierra GameKing Spitzer Boat-Tail Ammo delivers factory-grade precision and hunting performance in a round that feels handloaded. Built on decades of Sierra's proven GameKing bullet design, HSM pairs these classic hunting projectiles with carefully matched components to maximize accuracy and terminal performance—the kind of consistency you'd expect from meticulous handloading but ready to shoot straight from the box. If you're running a 7mm STW and demand ammunition that respects both your rifle and your quarry, this is the real deal.

The 160-grain Sierra GameKing Spitzer Boat-Tail bullet is engineered for controlled expansion and deep penetration on medium to large game. The boat-tail profile reduces drag and supports flatter trajectories and energy retention downrange, while the spitzer nose and GameKing construction keep expansion predictable. HSM's component matching—powders, primers, and cases selected specifically for each caliber and bullet weight—means every round out of the box performs like ammunition built by someone who cares about consistency.

Whether you're hunting elk, deer, or pushing distance on the range, 7mm STW shooters know this caliber can deliver. Load these rounds, trust the engineering, and focus on your shot. Twenty rounds per box.

Frequently Asked Questions

What is 7mm STW and what game is it good for?

The 7mm STW is a powerful magnum rifle cartridge designed for medium to large game hunting and long-range shooting. The 160-grain GameKing load strikes a balance between velocity, trajectory, and bullet performance for elk, deer, and similar-sized quarry.

What makes the Sierra GameKing bullet design special?

Sierra GameKing bullets have a long track record in hunting ammunition. They're built for controlled expansion on impact—the bullet opens reliably without fragmenting excessively, delivering deep penetration and consistent performance across a range of distances and target angles.

Why does HSM claim this ammo performs like handloads?

HSM matches each component—powder charge, primer, and case—to the specific bullet weight and caliber. This precision manufacturing ensures consistency from round to round, similar to the care a handloader would invest in their own loads. Better consistency generally means tighter groups and more predictable ballistics.
