Most accurate Vihtavouri powder for heavies in 223 Rem?

Of course it varies from rifle to rifle, but... Which VV powder have you had best (most accurate) results with using 88-90 gr projectiles?

Thank!

I'd stick with N140 or N540.
Below is VV data for separate loading lengths.

I can confirm. I used both for F-Class and PRS when I shot 80s and 90s. I got a bunch for a steal when my local range changed management and decided to no longer sell components. If I remember right they were selling the VV powders as low as $5/pound by the end. I bought 30-40 pounds of it.

I typically used Varget, N140, RL17, and a few others. N140 seemed to give the most consistent results. RL17 gave the best velocity with acceptable grouping. Varget was in the middle for both.

N140 is easy key.
