When self-proclaimed "experts" use ballistic/projectile information incorrectly - most common is SD - sectional density (not Standard Deviation which is a term related to statistics and useful for evaluating velocity consistency).
So, the phouck-tard wanna-be expert presumes that SD is the end-all, be-all measurement for determining a given bullets effectiveness on game (as if the dimensional relationships actually determine rigidity of a projectile..... they sorta forgot that rigidity of a projectile is primarily determined by it's materials and construction...duh).
And nearly as bad is when they concoct relationships between terms like BC - ballistic coefficient, SD, and presume those dreamed-up relationships actually have some "real-world" basis in fact....when they obviously do not....
Also, prideful old gits who think they know something, but actually forgot most of what they larned 30 years ago and blend the rest into some strongly-held scientific treatise based on empirically determined physics (resulting in wanton self-reflection.....like right now. ugh).
