For the price, having the tips not already assembled is not a great selling point.
I do often see Hammer bullets used for test targets for rifles such as Cooper.
I don't see the shedding petals as something I would look for in a hunting bullet. There are times when a perfect shot angle just isn't happening. I'd want to know the bullet had as much expansion possible while retaining most of the weight. I'm ok with an occasional shear off of one petal on heavy bone. But not ok with just a caliber size bullet driving through to the exit
