I went out and tested Swedish ball in several Swedish M1896's and then developed a load that was approximately the same velocity and the same bullet weight. My load with 43 grs of 4350 shot very well in all rifles. I did post a 100 yard target from my M700, considering that it is a light weight sporter, the group is more than adequate for a hunting rifle.
In modern rifles, you can push the pressure and velocity envelope, but in vintage military rifles, stay within vintage pressures and velocities. You can also see just how much faster a 29 inch barrel will push the bullet given the same powder charge. Very impressive.
