Your post said it shot MOA. I would never mess with MOA in a hunting rifle. If you remember what you were using I would try that load again. Many years ago I set up a .338 Winny on a Mod. 70 "Classic Stainless" action. A near perfect gun for Alaska that always performs well. But, I also have a very good Pre-64 Featherweight 30-06 that shoots 168 grain Barnes TTSX bullets MOA. That load is plenty of the "right stuff" for any Alaskan critter.
I had a guy put and Old English recoil pad on it, recut the checkering and apply a good oil finish and inlet some super Grade swivel studs and added a cross bolt and ebony forend and grip cap and bedded the action and floated the barrel. The trigger breaks at a crisp 2.75 pounds average on my Lyman trigger pull gage. The Talley bases feature a Brockman's pop up receiver sight and the scope is in Talley QD rings. That grand old Winchester Featherweight 30-06 would be the last bolt rifle I would part with.
I don't remember reading any thing negative about the Hornady ELD X bullet.
