Speer Grand Slam .243 Caliber 100 gr Soft Point Bullets (Speer part no. 1222) give handloaders a component-grade .243 Caliber projectile built around a tapered, fluted jacket that gives symmetrical big-game expansion. Speer designs the Grand Slam line as a big-game rifle bullet built for high retained weight, and this box of 50 lets you work up loads without guessing at bullet quality. Each 100 grain soft point is manufactured to the same tolerances Speer uses in its own loaded ammunition, so pressures and velocities stay predictable batch to batch. It is a straightforward, confirmed-spec choice for the bench, not a mystery bullet. Find it filed under our reloading bullets selection.
