Sierra 270 Caliber 175 Grain TGK Bullets - 500 Count Box

The Sierra 270 Caliber 175 Grain TGK Bullets are built for reloaders chasing long-range performance on big game. At 175 grains, Sierra's Tipped GameKing is a heavyweight round for the .270 Winchester and magnum cartridges, engineered to deliver the velocity retention and downrange energy that serious hunters demand. The polymer tip and boat-tail design aren't just for looks—they work together to maintain a high ballistic coefficient throughout the flight path, so your shots stay stable and efficient even when distance stretches out.

These bullets demand a barrel twist rate of 1:8 or faster to stabilize their longer profile, which is something to verify before you load. That length is the trade-off for the high BC—the sectional density of 0.326 packs real penetration potential into a premium hunting projectile. Whether you're loading for open-country mule deer hunts or pursuing elk at elevation, this is a bullet that's designed to perform when conditions aren't ideal and range is part of the equation.

You'll get 500 bullets per box, so you've got enough to develop a load, test it, and hit the field with confidence. Sierra's quality control on these is consistent, which matters when you're working up precision loads. Reloaders who've moved beyond standard cup-and-core projectiles will appreciate the engineering behind the TGK line.

Frequently Asked Questions

Will these 175-grain bullets work in my .270 Winchester?

Yes, these are designed specifically for the .270 Winchester, but they'll also load in .270 magnum cartridges. The critical requirement is that your barrel has a twist rate of 1:8 or faster—check your rifle's specs before loading to ensure stable flight.

What twist rate do I need to shoot these bullets?

You need a barrel twist of 1:8 or faster to stabilize the 175-grain TGK's longer profile. Slower twists may not stabilize them properly, which will hurt accuracy and performance. If your rifle is twist-restricted, a lighter Sierra .270 bullet would be a better match.

How many bullets come in a box?

Each box contains 500 bullets, giving you plenty of ammunition to develop a load, practice, and hunt with confidence.

What makes this bullet good for long-range hunting?

The high ballistic coefficients—.560 at velocity, stepping down to .485 at lower speeds—mean the bullet resists wind drift and velocity drop better than lighter projectiles. The polymer tip and boat-tail design work together to maintain stable flight, so you retain energy and accuracy at distance where it counts most on big game.
