I have used Gold Tip arrows for years now. I currently use XT 5575's for my hunting arrows. The other day, I picked up a half a dozen brand new shafts at an auction and I was wondering if I could use them for deer hunting or not. They are Gold Tip Ultra lite's. They don't have a number that I'm used to, like 5575 or 3555 they just say Series 22 on them. Are these shafts tough enough for hunting, or is this just a target arrow?

Thanks!
