[ARCHIVED THREAD] - Short Barrel Velocities Data needed

Posted: 2/15/2003 12:27:47 PM EDT

There's plenty of research and documentation of how the 5.56 performs at barrel lengths to 14.5 inches over on the AR side. My project is to end up with a 12.5 inch barrel in 5.56 and 7.62x39. What data is there out there that involves this length with these cartridges? I'm especially looking for the 7.62 data, as it's less common. Thanks
