[QUOTE="CaneBrake, post: 2938067, member: 127859"] Mass does play a big part. Center of gravity and Center of Pressure are things to consider but only once the bullet is not stabile and we do need to know them to figure out what the bullet needs to become stabile. You are correct, that is another reason longer bullets are harder to stabilize. We are trying to make sure the bullet is gyroscopically stabile so that the center of pressure offset from the center of gravity is nearly eliminated. Mass is going to factor into how much moment of inertia the bullet has. That's also why bullet construction matters because the distribution of its mass also changes its moment. [/QUOTE]
