Why is the 25-06 slower then the 30-06 with the same Bullet weight?

[QUOTE="Browninglover1, post: 539361, member: 29966"] The difference in velocity does have to do with pressures. A 115 grain bullet in a 25 caliber is going to be lots longer and have much more bearing surface that produces friction than a 115 grain bullet from a 30 caliber. The more friction that is created causes higher pressures and does not allow you to achieve the same velocities with the same weight bullets in your example. That being said, the 25 caliber bullet will have a much higher BC and should fly much better at longer ranges than the 115 grain 30 caliber bullet. [/QUOTE]
