Well, depends on what type of bullet. With 150gr Sierra Prohunters, they do great on big deer, but don't seem to do the damage on smaller 80lb cull deer. With 150gr Sierra Gamekings, they almost work flawlessly at 2600fps or less. 150gr nosler partition, 150gr coreloks, 150gr Speer,etc, etc. There is alot of softpoints out there. Some made for elk, some for deer. etc.
