Developing a new Load


Directions: Generally when you develp a new load you will start with a 10% reduced load. With the below formulation sheet all you have to do is enter the listed MAX load from your favorite loading book and it will calculate the next 5 reduced loads for you. Enter the Powder's VDM and it will calculate the CC powder volume automatically for you. All numbers currently entered are examples only. Enter MAX load here
I assume no fault for any miscalculations. Use this calculator at your own risk.

Max Load Starting Load Powder VDM Load #1 #2 #3 #4 #5

You can find the VDM of your favorite powder in most load books. I also have some listed at http://www.BRLeather.net/ReloadingData.html
