I used to load up with the newest "magic bullet" every year, and I have killed piles of deer with them. However, you certainly don't need them. Core-lokts, powerpoints, etc will work fine. That said, premium bullets tend to shoot better in my rifles, and I like the added confidence that they give me. I think that a few more bucks for components or factory loads is cheap insurance when you consider the cost of a hunt, local or abroad. Also, anything that I can do to deloiver a quick, painless death to the deer, I am all for. Just my 2c
