I don't pull any bones, on what is fact with this round. I love my 300RUM. But I am honest saying it is finicky a cartridge I have seen. Just another toy for me. I would defiately buy it over any Weatherby. I have never used it on elk, but bet it will be a dandy. All of the moose I took in Newfoundland were far. Well over 200 yards. And I wanted that downrange energy from the 300RUM with a 200gr bullet. And I did get a pass thru on one. Which I thought was quite impressive at such a distance. I doubt I will be going back to that island for moose, but plan on using it on elk soon in Colorado. I never did get a shot at a nice >40" moose. And I have about given up on them in newfoundland.
