I have used them in the 30-06 and 308 as well . One time I ended up with a disputed deer when two of us shot at the deer and when we dressed it out the little green tip was in the gut pile next to the heart. I was the only one shooting the little green tip bullets. I gave it to the other guy anyway as it was his last day to hunt and I still had a week left to hunt. I never let work get in the way of hunting seasons.
