[QUOTE="codyadams, post: 1552461, member: 87243"] The reason a 26 nosler takes more powder to move the same bullet at the same speed is because it has a larger chamber to fill with pressure to get the bullet up to speed. Think about it this way - throw a firecracker into a pop bottle and put the lid on, when it goes off it is likely to shoot the lid off at a pretty high velocity. Now, put the same firecracker in a large air tight container like a tupperware container, and fit it with threads and the same bottle cap. It will not have the same affect, as there is much more space to fill, it would take more fuel to have the same bottle cap affect. Same goes for a 26 nosler vs 6.5 creed. The reason why the same bullet, going the same speed, recoils more when using 80 grains of powder vs 40 grains of powder, is muzzle blast. The bullet itself causes some recoil, but the bullet is not the only thing generating recoil. When the bullet exits the barrel, there is still unburned/burning powder coming out the muzzle at very high speed, thus creating rearward thrust, similar to a rocket as Rich Coyle stated. The more fuel burning, the more thrust created, therfore 80 grains creates more thrust (felt recoil) than 40. Muzzle brakes create a surface for this "thrust" to blow against, therefore turning some of the rearward thrust into forward thrust, and in doing so reducing felt recoil. That's why brakes work.
