Hornady loaded this .270 Winchester with a lot of careful engineering to get you flatter shots downrange without beating up your rifle or shoulder. The 130 grain Superformance load runs at 3,200 fps, which is about 100 to 200 fps faster than conventional ammunition, thanks to Hornady's progressive propellant technology.
The real difference is in the powder formula. Superformance ammunition uses custom-engineered propellants that burn more efficiently in each cartridge, optimizing both burn rate and pressure curve so you get serious velocity gains while staying within SAAMI pressure limits. That means faster shots, not harder recoil or excessive wear on your barrel. Temperature stability is another advantage, so the round performs consistently whether you're hunting in cold mornings or heat.
The 130 grain SST (Super Shock Tip) is built for hunting at distance. A red polymer tip creates a higher ballistic coefficient for flatter trajectory and less wind drift. On impact, that tip drives back into the lead core to start rapid expansion. Hornady's Interlock ring mechanically locks the jacket to the core, preventing separation during penetration so the bullet holds together and maintains weight through the vitals. The secant ogive and boat tail further refine ballistics for consistent performance.
You're getting Hornady's quality casework and primers here, which matters for consistency shot to shot. The 130 grain weight balances velocity with energy for medium-sized game out to extended ranges. The flatter trajectory from that extra velocity means you're compensating less for wind and drop, especially valuable when you don't have time to range or calculate holdover.
Superformance uses progressive propellants that burn more efficiently and completely within the barrel, optimizing the pressure curve. This delivers up to 200 fps more velocity while chamber pressure stays within SAAMI standards, so you get the speed without extra felt recoil or barrel wear. The propellant design is tuned specifically for each cartridge.
The 130 grain SST is designed specifically for deer-sized game. The polymer tip initiates controlled expansion on impact while the Interlock ring locks the jacket and core together for reliable penetration. The flatter trajectory from this load's velocity gives you better accuracy at longer ranges where deer hunting often happens.
Yes, Superformance rounds are safe in semi-automatic rifles. However, Hornady tests show that rifle-length gas systems with barrels 20 inches or longer work best. Shorter carbine-length gas systems may benefit from adjustable gas blocks to manage the propellant's longer pressure duration.
The 130 grain load favors velocity and flatter trajectory, making it excellent for deer at typical hunting distances with lighter recoil. The 140 grain version carries more energy downrange and is often preferred for larger game or longer shots where that extra momentum matters. Both are accurate with the SST design.
