Mine shoots Nosler 165 gr BT's pretty well out of a magnum sporter profile barrel and I have a load for both IMR4831 (more speed) and H4831sc (less vertical). I have used both WInchester and Norma cases. I like Norma best - better case neck consistency and drilled flash holes, but expensive. I use Fed 210M primers and have had no ignition issues. Both of these shoot well about a half grain under Nosler book max. And I load them longer than the 2.86" book length, but you'll need to fool with seating depth based on your chamber and barrel. I did notice that pressures seemed to rise as I loaded them longer, so go slow and careful...
Currently shooting a 180 gr Accubond load with H4831sc that's looking pretty decent.
