Mag. Today is loaded with many additional bullet weights. Reloder 25 is about the slowest I’d go with the 7mm Rem Mag. Reloading for the 7mm Rem. How I reload; Reloading Questions; About. The sharp point of the SST projectile increases the ballistic coefficient making it fly faster delivering more energy on impact.
