The Sellier & Bellot .257 Cal 117 Grain SP Bullet pack provides handloaders with purpose-built reloading projectiles for the classic .25-35 Winchester and European 6.5x52R cartridges. Engineered with a semi-jacketed soft point profile, each bullet combines an exposed lead core with a CuZn 10 brass-alloy jacket designed for uniform mushrooming and reliable terminal expansion on game. Supplied in a box of 100 components, these unprimed projectiles feature a true .257-inch diameter specifically shaped to match the feeding requirements and twist rates of classic sporting and lever-action rifles.

Key Features

  • Controlled Expansion: Utilises an exposed lead tip and drawn CuZn 10 jacket to deliver consistent expansion and high weight retention upon impact.
  • Cartridge-Specific Profile: Sized to an exact .257-inch diameter with an ogive tailored for vintage lever-action tubular magazines and European break-action platforms.
  • Aerodynamic Balance: Delivers a G1 ballistic coefficient of 0.223 and a sectional density of 0.253 lb/in² for stable flight and penetration at moderate hunting velocities.
  • Bulk Reloading Supply: Packaged in quantities of 100 projectiles per box, yielding a total package weight of approximately 0.76 kg for bulk handloading batches.

Who is the S&B Sellier & Bellot .257 Cal (6.5x52r, 25/35 Win) 117 Grain Sp Bullets 100 Pack for?

  • Vintage lever-action handloaders — chambering classic .25-35 Winchester rifles benefit from this reloading soft point bullet's traditional .257 in profile and 117 grains weight, matching original chambering tolerances and magazine feeding limits.
  • European combination gun hunters — handloading for 6.5x52R break-action kipplauf or drilling rifles require this specific .257 in diameter soft point bullet to correctly match nominal bore dimensions rather than oversized standard European 6.5mm bores.
  • Short-to-medium range game hunters — targeting small-to-medium species at distances up to 150 metres rely on this 117 grains projectile's G1 = 0.223 ballistic envelope for dependable expansion and retained terminal energy.

Less suitable for: Target shooting or hunting engagements at distances beyond 150 metres, where high-ballistic-coefficient boat-tail spitzer projectiles are required to counter rapid trajectory drop; or for rifles with standard .264 in (6.5mm), .243 in, or .270 in bores that require strictly matched projectile diameters.
