But that's the beauty of those LRAB in that you can run either the 150 or 168 LRAB and still have super high BC's and drive em fast too. I'm a deer hunter so I wouldn't need to use a heavier bullet than either one of those. Might be a little less recoil too using the lighter slugs. One of the loads on Noslers Load Data site calls for 78 or 79 grs of IMR-7828ssc that will drive those 150's at over 3300 fps whereas a lot of the other loads that get top velocities are using 90+ grs of powder. More muzzle blast, throat wear and barrel wear I'd imagine pushing 90+ grs of powder every time you launch a slug down the tube. The standard 160 gr Accubond has a BC of .531. The 168 gr LRAB has a BC of .652 which I believe is higher than the (162) AMAX's. If I were chasing down Elk, I rather be using an Accubond over an AMAX.
