here is the response I got from Hornady today on the velocity thresholds for the SST and Inter bond bullets:
"The SST (Super Shock Tip) bullets are made to open up fast and give high shocking energy for quick kills. They open at lower velocities around 1500 fps impact.
The InterBond bullets will open twice the diameter and need about 1600 fps to open out to twice the diameter.
They retain 80 to 90 percent of original weight for penetration. "
I have had better luck accuracy wise with the inter bond bullets in my .300 so maybe I will check those out for the Grendel as well.
