On the right hand side of the button bar is 'Ballistic'. It will do the business for you.

If you want details, the 150gn ORyx has a BC of .373. JBM Ballistics indicates that your PBR Zero is 285yds with a 12in vital zone.

Uncle Nick's table in the back of his reloading manual says 354 yard PBR with the 150g bullet out of the 270, but does not give a speed. :wink:
