Re: How well does it penitrate and expand?
They function much like the Berger, I'm running mine right now at 3060fps. I shoot elk behind the shoulder 99% of the time and at close range under 500 yards or so they go in then slow blow and may or may not exit, sometimes you'll see where bullet chunks bounced of the off side but everything inside will be a mess! Once you get out beyond that they start exiting more and more. By 900 yards I get 100% exits even on shoulder hits, they make a hole through them like you shoved a meat grinder through them. They are extremely effective on elk!! I've only seen one deer hold a 165 Matrix!!
