Sierra 270 Cal 175 Gr TGK Bullets - 100/Box

The Sierra 270 Cal 175 Gr TGK (Tipped GameKing) bullets deliver serious power for handloaders chasing big game at distance. At 175 grains, these are built specifically for the .270 Winchester and magnum cartridges, engineered to perform when it counts on elk, moose, and other heavy-framed animals. The high ballistic coefficient and aerodynamic tipped design keep velocity and energy downrange, so you're not losing momentum between the bench and the target.

What sets these bullets apart is their construction for demanding hunting scenarios. The 175-grain weight in a .270 caliber (.277 diameter) creates a sectional density of 0.326, giving you the penetration and terminal performance hunters expect from a premium big-game projectile. Because of their length, you'll need a 1:8 twist rate or faster to stabilize them reliably—check your barrel specs before committing to a loading.

Sierra publishes three ballistic coefficients depending on your velocity window: .560 at 1900 fps and above, .530 between 1570 and 1900 fps, and .485 at 1570 fps and below. That means you can dial in realistic trajectories for your setup and trust the numbers downrange. Each box contains 100 bullets, giving you a solid supply for load development and hunting season. If you're pushing magnum velocities or working up a long-range .270 load, these TGKs are worth serious consideration.

Frequently Asked Questions

What twist rate do I need for the 175 Gr TGK?

These bullets require a 1:8 twist rate or faster to stabilize reliably. If your barrel is a 1:9 or slower, these are not the right choice for your rifle.

Will these work in my .270 Winchester?

Yes, they are designed for the .270 Winchester, though the 175-grain weight is on the heavier side for standard .270 loads. They also perform well in .270 magnum cartridges and will handle the velocities those rounds deliver.

What is the ballistic coefficient, and why does it matter?

Ballistic coefficient measures how efficiently a bullet cuts through air. The 175 Gr TGK has three BC values depending on velocity: .560 at 1900 fps and above, .530 between 1570–1900 fps, and .485 below 1570 fps. The higher BC means less wind drift and velocity loss at extended range, so your bullet retains energy and accuracy downrange.

How many bullets are in a box?

Each box contains 100 bullets, giving you plenty for load development and a full hunting season.
