What grain projectiles are you shooting?

At Engel Ballistic Research, we use a variety of projectile weights for different applications. You will find that heavier projectiles are used in our subsonic ammunition than are used in our high velocity (supersonic) ammunition, including our frangible line. For example in the .308 Winchester caliber we utilize a 180 and a 175 grain projectile for the two different rounds we offer, while we use only a 125 grain projectile for our frangible in the same caliber.
