Ok,since there's no ammunition forum maybe someone can help me out.I have a question. I've been shooting Remington's 150gr core-lock. My rifle is a Rem 700 300-06 bolt. Why is my round making such a big hole. Or it's blowing up and there's 3 exit holes. I was shooting 180gr. So i went down to 150's and it blew a hole the size of a grape fruit in a doe? I just want to harvest a deer not blow it up!!
