so I have contacted hornady with no response so I'm wondering if anyone has a load for the 30-378 using the 220 eldx over h1000 thanks in advance for any help
Try Retumbo also. Retumbo performed much better in my 30-378 with the heavier bullets. Unfortunately the ELDX wasn't as accurate as the 215 Berger Hybrid. Good luck
I would bet 98 grs of H-1000 would be almost right.... as that is load using the 215's.... But maybe start just a bit lower depending on your seating depth and freebore...
