I have some that I really enjoy, they are in order of my preferences: Each clock between 1000-1100 fps with 250g Keith bullets in .44 mag cases:
.44-250Keith/12.0g AA#5/WLPP/Rem Brass
.44-250Keith/10.0g Unique/WLPP/Rem Brass
.44-250Keith/8.5g Bullseye/WLPP/Rem Brass
Of these the AA #5 load seems to be the most consisten and least prone to leading if the bullets aren't hard enough. It has a lower flame temperature and lower/longer pressure curve than either Unique or Bullseye. Very accurate in my guns as well as other guns used for testing over the years!
Hope this helps! Soon we'll have LoadSwap available for online loading data from our user driven loading databse.... should make this kind of information more readily available!
God Bless,
Marshall
