To me, there is a clear distinction between an inherently accurate roundball caliber (which the title of this thread infers) and a roundball caliber that for a variety of other reasons like, recoil, amount of charge, muzzle blast, et al may be preferred by target shooters. Now, I am FAR from a ballistics expert, but it seems to me, from a aerodynamics point of view, a ball is a ball. Whereas, without treading too deeply into the non-black powder pool, clearly things like ballistic coefficient, length of bullet, etc, significantly contribute to accuracy in that world. Is this not so?
