[QUOTE="BryanLitz, post: 294072, member: 7848"] Stability can be a tricky thing because it can depend on your altitude and air conditions. You can be confident that the 95 VLD will stabilize from your 1:9.3" twist. The 105's ... it depends. If you're shooting in warm summer conditions at high altitudes (low density air), then they might work. However, if you're at sea level in the winter, they won't. If you decide to try the 105's, I recommend testing them in the lowest temperature, and at the lowest altitude that you expect to hunt with them in to insure they'll work when you're hunting. Worst case scenario is that you work up a load in the summer that shoots great, but is borderline stable. Then you don't shoot again till winter, and your bullets are not stable in the colder (denser) air. I've seen some terrible arguments between people who claim that a certain bullet/twist combination is stable in certain conditions, where others claim it's not. The root of the disagreement is that the people are all shooting at different altitudes! I know a guy in Pueblo, CO (~5000 feet above sea level) who shoots the 105 VLD's from a 1:10" twist barrel with great accuracy. Don't try that at sea level! If you're interested in calculating bullet stability for a particular set of atmospheric conditions, I can email you a free simple program based on the Miller stability formula. Send me an email at: [email]bryan.litz@bergerbullets.com[/email] and I'll reply with the program attached. Take care, -Bryan [/QUOTE]
