[QUOTE="akmtnhnt, post: 2357190, member: 120824"] Stability has very little to do with weight. It's mostly length. A 180 lead is a lot shorter than a 180 copper. Secant or tangent ogvie will also matter quite a bit, as a tangent ogive will be shorter than a secant for the exact same weight. So you might be able to get away with a heavier tangent ogvie copper bullet in a slower twist barrel, at the sacrifice of some BC. Similarly, a WFN cast lead bullet will stabilize in a very slow twist barrel, with the BC of a barn door. There's a reason you see things like 45-70 or 44-40 with a 32 twist. You can pretty much know if a bullet will be stable before you load for it. And you don't really have to take the word of the manufacturer if you don't want to. Maybe you do all your hunting above 10k ft when it's 100F out. That's going to change things a good bit [URL unfurl="true"]https://bergerbullets.com/twist-rate-calculator/[/URL] [/QUOTE]
