I've got a bunch of ELD-M 123s so that's what I'm using. I might load up some SMK 123s too.
Moly doesn't work that good, it's messy and it can form cakes in your bore because it breaks down at high temperatures. David Tubb believes in hBN to the point that he's selling hBN and coated bullets, but other professional shooters claim good results with it too. If the hBN coating is effective you'll typically have to increase the powder charge around 2% because the reduced bullet friction results in lower pressure and lower MV. I'm mostly trying it for increased barrel life and easy bore cleaning, but there's a case which can be made for coated bullets exiting the necks uniformly and reducing the incidence of fliers. Supposedly your first shot with hBN will be in the group with subsequent shots.
