However - Bryan Litz appears to have tested it, and the results appear possibly different to the "conventional wisdom".

I have not tested this nor looked into it sufficiently. I select a powder based on:

1. Is it ADI, and therefore actually available and affordable?
2. Does it give the highest or close to highest MV out of the ADI book?
3. Is it widely and successfully used in the relevant cartridge?

Using these criteria eliminates the problem.

I have yet to see any genuine evidence that once an appropriate powder is selected, different charge weights actually produce a different velocity SD, all else being equal. If anyone has any, please post it.

I have data sets that suggest the opposite.

Any process that purports to allow one to select "the best load" by default also should allow one to deliberately select "the worst" and demonstrate that they are different. I am keen to see people provide evidence of this. Without evidence, we're all just another bloke with an opinion.

Read what I wrote above. Believe me, don't believe me I really don't care.
