I've shot mostly Sierra and Nosler bullets. The Sierra bullets have been consistently more accurate and effective for my targets of choice. Nosler bullets have been good, just not quite a good as Sierra. I'm a prairie dog shooter, mostly with .204, .223, 22Hornet. My Rem 700 VSF .223 has been deadly with 50 and 55gr Sierra BKs; with 1:12" twist. I bought the Tikka T3X Super Varmint .223 with1:8" twist to accommodate heavier bullets that will hold stability over longer distances; hence the search for 62 gr bullets. Friends of mine shoot long distance competitions and swear by 62 gr bullets through 1:8" barrels. All this brings me to why I search for Sierra 62gr.
Maybe Hornady would be just as good, but I would prefer to shoot what has worked in the past. As we say, "If it ain't broke, don't fix it." Plus, all of you guys know what an ordeal it is to start the process of loading a new bullet experimentally with different loads, powders, etc.
