Just in the load development for my 6mm/284. Built on a trued Remington 700 Short Action, with Hollards heavy competition recoil lug, Pac Nor Super Match 30 inch 3 groove 10 twist barrel and 8.5 - 25x 50 LRT Leupold.
Started load developent with 87gr V-Max's & H1000, and shooting 1/4 min groups, so I know that my rifle likes this particular bullet. Powder weight was 56.5 gr's, but velocity quite low. When I started loading up to 59 gr's, velocity was better, but accuracy suffered.
I know from other people with 6mm/284's that this powder is too slow, I have been advised to stick with H4831 and H4350. What other advice can you give.

My 6/284 has a 8 twist barrel on it for the heavier bullets so i don't know how your gun will react but RE22 worked well in it.

I go along with "lynn". Reloader 22 works great in my 8 twist w/Sierra 107s. Start w/about 45.0 grains

I too have a 6mm-284 on a remington with 10 twist barrel. I tried about every powder I could think of and for my rifle the VERY BEST VV N560. Bar none! Any bullet weight performs best in this rifle with that powder. And boy is it fast! Try it, it might work that well for you too. Hope so.

My lightweight rifle shoots very well with 85 grain solid bases and 51 grains 4350. Took a couple of bucks this fall with that load. Also had good luck with heavier bullets with RL-22 and 4831 sc.

I've heard a lot of folks sing the praises of RE-22, but I haven't used it since experiencing an unpleasant surprize with it about 2 years ago when Alliant put out 2 lots of the stuff that was WAY faster than it should have been, almost like RE-15. When I reported same to Alliant their response was, "Well yeah, but it's still within our specifications for that powder". That told me that their "specifications" were far too loose for any kind of competitive shooting.
Since then, I've used VV165 or 160 exclusively with excellent results. The groups mentioned in the 108 Euber thread over in the bullet & ballistics forum were shot with VV165. It has been very consistent lot to lot and produced the smallest velocity spreads (at least in my rifle) of any of the powders tried including H4831SC. As a side benefit 165 is about the coolest burning powder at that burn rate, which means better barrel life.

Should be getting my 6-284 Rem XP-100 (8 twist Broughton 5C) in a couple of weeks. Intend to use the 115 DTAC bullets and the 105 /107 VLD's too.
Any data with Hodgdon powders for the 115 grain?
