In my experience they tend to expand and kill things.
The 129 grain Hornady is one of the best 6.5mm bullets ever made. Even the reasonably priced Hornady American Whitetail factory ammo with this bullet in the 6.5 Creedmoor is MOA capable.
The last 3 shot group from my son's Ruger American Predator with 129 soft points measured .418. I was amazed. I bought the ammo on sale from Midway for under $20 per box
