I found this when reloading supplies were scarce and I was trying my best to work up a load for my new SPR build with minimal waste of supplies. In short, the theory is that you want the projectile to exit the barrel when the shock wave of the blast is furthest away from the muzzle. This will prevent it from disturbing the projectile as it exits the barrel. All credit goes to the-long-family.com for the theory. I believe this may explain the reason behind the accuracy nodes we see as we work up our loads. Of course you have to take your time measuring internal case volume and getting precise measurements of all of your input data but I love the intricate calculations involved. I guess it's time to buy some ballistics software! Has anyone else tried this theory?

That was an interesting read. I have been using Quickload for a while now. I got it to calculate some wildcat rounds I was playing with. I'm sure there are others, just keep in mind that the results are only accurate if you input the correct data.
