Rifle Ammunition - 277 Sig Fury, Elite Ball Fmj, 135 Gr, 2750 Fps, 20/bx

The SigArms 277 SIG Fury Elite Ball load is a 135-grain full metal jacket cartridge built for the next-generation rifle platforms chambered in 277 Fury. It runs at a muzzle velocity of 2,750 fps and ships 20 rounds to the box (MPN E277SFB13520). This is target and training ammunition rather than a hunting load, so it suits shooters logging trigger time on a 277 Fury rifle who want consistent feeding and a clean-burning FMJ projectile. Buyers stocking up on 277 Fury ammo for practice sessions will find this a straightforward range round. Browse our full ammunition lineup for additional rifle calibers.

What sets the 277 SIG Fury apart from conventional rifle cartridges is the hybrid case design SIG developed for the U.S. Military's Next Generation Squad Weapon program. The hybrid case pairs a brass body with a stainless steel base, which lets the cartridge run at higher chamber pressures than a standard brass case while keeping weight in check. That pressure ceiling is what drives the velocity numbers and the flatter trajectory the caliber is known for. The 135-grain FMJ Elite Ball projectile is a copper-jacketed full metal jacket designed for repeatable feeding and reduced bore fouling over high-round-count range days. With a UPC of 798681659821, each box of 20 is factory-loaded to SIG's Elite Performance spec for consistent velocity across the string.

Reach for this load when you need a dedicated practice round for a 277 Fury-chambered rifle and want to keep barrel wear and fouling predictable. FMJ Elite Ball is best on paper, steel, and general marksmanship work, not on game, where SIG's expanding hybrid hunting loads are the better call. Stash it in a sealed ammo can to protect it from humidity, especially in Florida conditions. When you head to the range, pair your stock-up with the right shooting rest to get the most out of the caliber's flat trajectory.
