Anointed weapon damage vs elemental

So between anointed 100% damage and next 2 magazines 50% elemental damage which is better ? I did some tests on my own and notice 50% elemental has more DPS than 100% damage, for example I hit graveward in head with 24k base and with 100 %annoint it was like 28k, but with 50% magazine one it was 24K+12K which is much better… is 100% annoint bugged ?
