[QUOTE="JTH, post: 2887535, member: 59647"] That’s right. If you want to shoot the heavy for caliber, higher BC bullets, solids will require more spin to stabilize due to their length. Lead is heavier than copper, so it takes a longer copper mono to get to the same weight as a jacketed lead bullet. Most of the solid mono manufacturers list a recommended barrel twist rate, stick with their advice or possibly even a little faster. Using a ballistic app, I’m plugging in all the data and looking for a minimum gyroscopic stability factor above 1.50, the higher the better for improved terminal performance, ideally closer to 2.0 [/QUOTE]
