For the higher velocities of the ultra mag I'd look to two bullets and use a 200 grain bullet in the Northfork or the Swift A-Frame.
I've used both on African plains game in a .300 H&H with great success and recommend both highly. They are a tad spendy but worth the extra IMO.
I've had no problems at all working up a load for either of these bullets using regular cup and core data from Hodgdons or Hornady loading data assuming we always start low and work up which we should be doing anyway! IIRC Northfork recommends starting 8% under max but so far I've always worked back to max loads without incident!
I'd not recommend any standard cup and core bullet in the ultramag (or any magnum for that matter) but would much prefer a bonded bullet of some type and the Northforks and A-Frames are "stand out" bullets that will not come apart at the higher velocities.
I've used Barnes a bit lately and that bullet has promise at the higher velocities but to date I've only range tested them and not actually killed anything with them. Others have high praise for them.
