Hodgdon recommends H4895 for the sort of loads you seek:

Note that they say "...we chose H4895 because it is the slowest burning propellant that ignites uniformly at reduced charges."
In their burn rate chart,

Varget (at #99) is a good bit slower than H4895 (at #87). Taken with the statement above, I'd say Varget wouldn't be a wise choice for reducing below suggested starting levels.
