Sierra 6.5 142 BC question

6.5 forever

Silver $$ Contributor
Sierra lists multiple BC by velocity. Does anyone know if the listed velocity is at the muzzle. I wish they would give us a G7 BC like some if the other bullet makers.

Those velocities start at the muzzle and the BC changes as the bullet slows down. If you use an app like strelok, you can input each banded BC. Even better, it has G7 BC's for many bullets preloaded in its database including the 142 smk

The G7 on this bullet must have been added recently. It is on there now as you say, and I have downloaded it. Thanks!!
