.308 | 200gr | Speer Grand Slam

About this bullet

.308 | 200gr | Speer Grand Slam is a bullet made by Speer. At 200 gr (13.0 g) and a diameter of 0.308'' (7.82 mm) it suits handloads where bullet weight and barrel length have to be matched carefully. Its G1 ballistic coefficient of 0.453 drives velocity retention and wind drift downrange — higher values mean a flatter trajectory at distance. A twist rate of 1:14.5 is recommended for stable flight; slower twists can under-stabilise this bullet. We currently list 1000 load recipes across 34 calibers for this bullet.
