I was looking for some .458 bullets today and overheard a couple guys yacking about how he needs high BC bullets, at least .625, and SD of .29 or better for his elk rifle. His buddy asked why and the guy says they shoot flatter and penetrate better.
I started to wonder how my bullets don't just bounce off or make 90 degree turns in full value 10kt winds. My favorite elk bullets have the BC of a racquet ball. The .308 180gr Partition, .338 250gr Partition, and the Speer .458 350gr come to mind. I looked it up, that .458 bullet has a BC of of .232.
I'm sure there are efficiency benefits, but at what point is it measurably "better"?
