Right front wheel grabs on dirt & gravel!

Put new brakes on & a used drum on( drum looks good, one light grove near edge) Right front wheel grabs on dirt & gravel, all springs are in right place on right side, adjusted bearing 1 time by feel, 2 times at 70inch pounds, steel douse same, tried adjusting brakes more, no change, its brakes even, but in the drive way on loose gravel or dirt it wants to grab putting on the brakes lightly. What do you all think, douse the drum may need to be turned?
