Opinions??????? Theoretical facts & figures, wow, Really? How long has Barnes been around, how much game has been killed with Barnes bullets? Much longer than your Hammer & etc!!! I just don't understand all of the Barnes bashers on this site, at least it seems to me like it. I'll take a Barnes any day over your other copper mono bullets! They're as successful, & more than most, as any bullet out there in the last 40 years or more. They do have a PROVEN track record, they wouldn't have been around as long as they have if not, search it for yourself. Enuf said. Sorry, didn't mean to offend anyone, but just had to give my 2 cents worth & that's probably all it's worth.
