Direct from Hornady, this is what they say to duplicate their factory ammo. This used to be on all their 140 Amax boxes. Per a conversation I had with them, it’s the same data for the 140 ELDM and 143 ELDX.
Don’t overthink it, jump and seating depth and ladder tests are all largely overblown BS. Put 41-41.5 grains of H4350 in a case with a large rifle primer (I use Remington 9.5 magnum primers even) and seat the bullet so the boattail junction sits right at the neck shoulder junction in the case and shoot it. Load up 10 rounds and shoot a group, I’d be absolutely shocked if it doesn’t shoot well.
