I don’t expect the gun to work; it seems to me that if Voldemort had a ritual to give people properties of magical creatures, he would have given them to himself, and firing a gun at a troll three times would not be terribly effective
The ritual only works permanently because he has the stone. He likely would have later transfered troll power to himself but I don’t think he has the time at the moment.
