I do not have a chrono, but the loading specs say 1545 fps. 1-1/8 oz. slug. I have put allot of them through my barrel, and had no leading problems. Every deer my daughters, and I have killed with them have passed all the way through the deer, and made a very nice wound channel on entry and exit. Nothing excessive, but a slightly mushroomed size hole on exit.
If you try them, you will not use anything else.
