I had the same thoughts as you about 30 years ago so I bought a new 760 in .308. It almost cost me a nice 8-point buck when I was hunting in sub freezing weather. First shot was a light strike on the primer. Second shot got him on the run. The rattle is also a dead giveaway. If you get one, you should strip it down and clean all of the factory lube out of it and use some graphite. That's what I should have done. Thanks...Bill.
