HRNDY SF 257ROB+P 117GR SST 20/200

Description

Hornady’s Superformance line was built around a specific problem: wringing more velocity out of standard-length actions without stepping up to a magnum case. For the .257 Roberts +P, that matters because the cartridge already sits at an interesting crossroads — enough case capacity to drive a 117-grain bullet to respectable speeds, but historically loaded conservatively by most manufacturers. Superformance propellants push past that ceiling, delivering meaningfully higher muzzle velocity than standard .257 Roberts loads while remaining safe in rifles rated for the +P designation.

The 117-grain SST bullet is the right weight choice for hunters who want a single load that handles deer-sized game cleanly across a wide range of distances. The SST’s polymer tip does two things simultaneously: it protects the nose profile during feeding and in the magazine, and it initiates expansion reliably at the velocities this load produces, including at the lower end of the speed range at extended range. The secant ogive profile retains velocity efficiently downrange, which matters when you’re asking a .257 to perform at distances where lighter, faster bullets have already shed significant energy.

Brass-cased and boxer-primed, these rounds are reloadable for shooters who want to work up handloads around the same bullet weight after the first firing. The 20-round box size is practical for range sessions without the overhead of a full case purchase when you’re evaluating this load in a specific rifle. Lot consistency matters for any precision rifle application, and buying in quantity from a single lot is worth considering if you find this load shoots well in your barrel.
