Actually, HP38 & W231 are the same powder, both spherical. Ball powders like AA#2 certainly meter better than any flake pwoder, but I have no issue getting 1/10gr accuracy using Unique. A lot of reloaders are just using certain powders for the wrong applications & that is what gives a powder like Unique a bad rap for being dirty. Still, some powders do leave more carbon or residue or unburnt powder behind. It doesn't have much to do with them being flake, stick or ball though.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
