.284 Bergers at 3000-3200 fps are one shot killers for Rocky Mountain elk and moose. I have used this bullet myself, watched my son (we use 140 gr or 168 gr), and my neighbor (168 gr and 180 gr with the latter at about 2800)all demonstrate the same results numerous times. I can't be made to believe they are not totally effective. The same neighbor shot a Yukon moose (I forget how it scored, but it was exceptional) at about 1000 yards with a 180 VLD from a 7 Rem Mag. Again a one shot kill. This video was on You Tube for a while but I don't know if it still is there as this occurred back in 2010 or 2011. This is not to say that there are not equal choices among the other brands of bullets but I tend to use what works for me in the field.
