There are just so many variables involved it would take a whole lot of statistically valid testing to prove one powder is more "accurate" than another,
Is it the powder? Yes.
Is it the bullet? Yes.
Is it the barrel? Yes.
Is it the primer? Yes.
Is it the ambient temperature? Yes.
In my 30-odd years of load development, rifle or pistol, I have found all of those things (and more...) have contributed to good or bad results. I do agree with Varmint, however...
Some powders seem to offer easier tuning and wider nodes (greater forgiveness) than others, across a wider span of cartridges, expansion ratios, relative bullet weights, etc.
There are a few powders that just work really well in a wider range of applications than another similar powder, but, again, it goes back to all of the other factors. For example, my most recent revelation was with TAC in the .308. Magnum primers vs standard primers made the powder act like two different powders... with results to match.
