The Sellier & Bellot .318 8mm 196 Grain Soft Point (SP) component bullet is an inert reloading projectile engineered specifically for handloading legacy European 8mm firearms. Manufactured with a true .318-inch (8.09 mm) outer diameter, this projectile caters to original "I-bore" (Infanterie) barrels, eliminating the compatibility and safety issues associated with using modern .323-inch projectiles in undersized bores. Featuring a semi-jacketed profile with an exposed lead core tip and a tombac gilding metal jacket, this 196-grain bullet delivers controlled expansion and mushrooming upon terminal impact, making it suitable for taking medium to large game at traditional bush ranges.

Key Features

  • True .318-Inch Bore Diameter: Specifically sized to 8.09 mm (.318 inch) to safely match the exact groove dimensions of vintage 8x57 I and 8x57 IR chambers.
  • Controlled Terminal Expansion: Utilises a semi-jacketed soft-point profile with an exposed lead nose, designed to mushroom reliably at moderate impact velocities between 1,800 fps and 2,600 fps.
  • High Sectional Density: The 196-grain (12.7-gram) weight yields a sectional density of 0.277 lb/in², providing the straight-line momentum needed for deep penetration on heavy game.
  • Ductile Tombac Jacket: Features an alloy jacket (Fe/CuZn 10 or CuZn 10) that protects barrel rifling while retaining core integrity during terminal impact.

Who is the S&B Sellier & Bellot .318 8mm Cal 196 Grain Sp Bullets 50 Pack for?

  • Handloaders of vintage 8x57 I and 8x57 IR European hunting rifles and combination guns — provides the exact .318-inch (8.09 mm) diameter required for original I-bore drillings and pre-1905 military actions that cannot safely chamber modern .323-inch reloading rifle bullets.
  • Hunters pursuing medium to large game at moderate bush ranges with legacy .318-bore firearms — uses a heavy 196-grain soft-point design with a G1 ballistic coefficient of 0.236, ensuring reliable terminal expansion and energy transfer across short-to-medium distances up to 200 metres.

Less suitable for: Modern 8mm Mauser rifles with .323-inch (8x57 IS / 8x57 IRS) groove dimensions where undersized .318 projectiles cause gas blow-by and accuracy loss, requiring dedicated .323-inch hunting bullets instead; or engagements beyond 200 metres where the low 0.236 G1 ballistic coefficient causes rapid velocity decay, making high-BC boat-tail or polymer-tipped spitzer bullets a better fit.
