It is not known very well in the US, but not necessarily well received. Anyone who has used one, will tell you that it has more than enough umph for any game in NA. Using 270 gr bullets at 2550 fps is a very potent round in anyone's book. Bullets can be had from Speer, Nosler, Barnes, Woodleigh, A Square, and others in various weights from 225, 232, 250, 270, 286, 293, 300, and 310 grains. Sectional density of the 232 gr is near .250, the same as 150 gr .308 bore.
