You may or may not get accuracy at 150 grains, many do not. I feel that accuracy is more important than maxing out the velocity, especially if you plan on shooting more than 100 to 150 yards. As for the Nikon Omega BDC scope, it is set up for a 250 shockwave style bullet at 2000 to 2100 feet per second, this may or may not match up to 150gr of powder depending on the gun used so don't caught in the hype of the press release because your gun may not match it. The gun and scope combination is a good setup but the aim points on the scope still have to be verified with the load you work up and shoot at the different ranges to make sure. Good luck with it.
