The 150 will be a little flatter at 300 yards than the 168.. But both will do the trick.. Also check out the 155 Grain BTHP from Federal... +1.6 at 100. Zero at 200 yds and - 6.9 at 300 and still 1900 foot lbs of energy at 300 yards.. I have been using the 85grain BTHP out of my 243 for years and it is wicked..
