Well, my old Chrony died a few months ago, and I haven't replaced it yet-so I don't know for sure. Closest estimate I can come up with is 1700-1900 fps (24" barrel). Penetration on the deer I shot could not be faulted. Although it didn't hit any heavy bones, the bullet entered the left side, right at the neck/shoulder junction, ranged down through the heart/lungs, skidded along the ride side ribs, and exited the right side flank, just behind the ribs. I scored about a dozen boxes of this stuff, at the local hardware store-at $6.xx something a box!
