I've used a few different VV powders, and besides the cost, the one thing that stood out was how clean they burn.

I noticed this especially in my SS .44 Mag pistols when testing loads, using VV N110 and Winchester 296.

The N110 loads were noticeably cleaner burning. It was then that I noticed that .45 ACP loads and Garand loads were also burning cleaner, it just wasn't as obvious with the dark metal.

The N110 loads were also very accurate.
