Pops, Hooligan is dead on, but nobody mentioned that the bullet you have is probably a Hornady SST instead of a true Ballistic Tip, which is a proprietary name owned by Nosler. And though the Nosler Ballistic Tip never was, and isn't, truly a hollow point bullet, the plastic tip does actually fit into a hollow point of the bullet. I've always believed that today's Nosler Ballistic Tip opens up a bit faster than the old Nosler Solid Base Boattail that it replaced, and that it's because the plastic tip gets forced down into the hollow point which opens the bullet up somewhat faster. That's what I think and have read, though it's by no means a fact. This is the internet after all...
