One of the best elk hunters I ever met swore by (and at) his bar. His thoughts were fast follow ups sure but follow up with NO NOISE of chambering the next round. He was a tracker, as was I and shot elk close in heavy timber and while they would jump up at the close shot they wouldn't know for sure from whence it had come.. If you then cycled a bolt their ears would pinpoint exactly where the danger had come from and off they would go at 40 mph. He was correct in this, I can tell you from personal experience. Of course the way around this is to never need the follow up.

He swore at it cause it was a heavy SOB for the EXTREMELY physical sport of elk tracking successfully. I was toting a BBR that tipped the scales at 10 lbs so i did not give him my shoulder to cry on, Now that I am his age i understand why I should have.
