[QUOTE="Mikecr, post: 864678, member: 1521"] You got it all backwards, it's stability that is decreasing with lower BC -for a given bullet. Stability is challenged by higher air density, which is analogous to lower effective BC. You also assign way too much value to the Miller twist rule-of-thumb. It is merely bell curve graphing of typical bullets/twists used today. As you near any edge of this, the results do fall apart, as with any bell curve. It's a useful tool, but don't confuse it with truths, or 'rules'. It's nothing like that [/QUOTE]
