7828 gave me the most consistent velocity and accuracy. My gun loved it. Older 340 Weatherby.
powder for 340 weatherby?

I recommend Norma MRP .
That is what factory Weatherby ammo ran on for years . Gets the most velocity with least pressure , and I found it to be somewhat tolerant to temperature changes . With freebore at factory specs , 3030 FPS with 250 gr. Sierra Game King , and 250 gr. Nosler partitions , Weatherby or Norma brass , and Federal 215 primers .

I would definitely try RE25, the temp stability issue with it just isn't there.
I use it in 25-06, 264WM, 270 WBY, 300WM, 300 WBY, 300 RUM & 340 WBY (When I had one).
It is an outstanding powder that gives very uniform and low ES/SD numbers and produces higher velocities with less pressure.
It is far less erratic than RE22 or Supreme 780 when max pressure is approached.
Cheers.

Well, it was there. Bought some not that long ago.....

I like H1000, Retumbo, and RL33. I like the RL33 the best because it is a nice slow burning powder that fills the case better yielding a more even consistent burn.
Hey just wondering if you still have the load data on your 225 with the vv560? Just looking to build up a similar load
