Hodgdon made small packs of similar burn rate powders at one time....haven't seen those for a while though.
Primers - 100 at a time is about as small as your gonna get
What you need to ask yourself while developing loads is this: Can you really make the groups any smaller? Are you, your equipment and the load capable of shrinking group size?
You'll find that instead of constantly chasing that "magic" load/combination, you'd be better off settling on a good one and shooting LOTS of it.
