As stated in the Barnaul thread I was playing with a chrony to day so I'll post some more data. I bought some of this new Federal Spitfire ammo the other day at Gander Mountain, it says that it has a MV of 1500FPS with a 31 gr bullet. I am assuming that is out of a rifle but I got some impressive results out of my 22/45.
