When you step into 270 Winchester territory, you expect velocity and terminal performance in equal measure. HSM delivers that with the Tipping Point 2 line — 150-grain Hornady SST polymer tip bullets seated in reloadable brass, primed with non-corrosive boxer primers, and loaded to 2813 feet per second. The SST (Super Shock Tip) features a sharp polymer nose that drives rearward on impact, initiating rapid expansion while the InterLock ring system holds the core and jacket together for reliable weight retention. Muzzle energy sits at 2635 foot-pounds, and the 0.525 G1 ballistic coefficient keeps the trajectory flat out to 300 yards. This is 270 Winchester ammo engineered for deer, pronghorn, and black bear — not plinking.
Built for the Box
HSM manufactures the Tipping Point 2 line in the United States with match-grade attention to case prep and powder charge consistency. The 150-grain Hornady SST is a secant-ogive, boattail design — aerodynamic profile reduces drag, increases bearing surface, and stabilizes in flight. The polymer tip does double duty: it boosts the ballistic coefficient and serves as a mechanical ram on impact, driving into the lead core to start expansion. The mid-body cannelure locks the bullet in place during crimping and holds the core-jacket bond during mushrooming. Brass cases measure within SAAMI spec, primer pockets are uniformed, and flash holes are deburred. Each round is visually inspected before boxing. You’re pulling from a lot that passed dimensional checks and velocity testing — not a budget bin.

This load fits standard SAAMI-spec 270 Winchester chambers — bolt-action and semi-automatic rifles alike. The 150-grain weight splits the difference between the lighter 130-grain flat-shooters and the heavier 150-grain penetrators, giving you a balance of retained velocity and sectional density for medium game at 200–400 yards. Shop the full selection of 270 ammo for alternate bullet weights and styles.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Follow the four rules of firearms safety at all times — treat every firearm as loaded, never point at anything you do not intend to shoot, keep your finger off the trigger until ready to fire, and know your target and what is beyond it.
- Verify that your state and local jurisdiction permit the purchase, possession, and use of this ammunition before ordering.
- This ammunition contains lead, a chemical known to the State of California to cause cancer and reproductive harm under Proposition 65. Store in original packaging and wash hands after handling.
