The old PC I had quickload on died and the replacement has Windows 8 and the 4 year old version of Quickloads of course doesn't work with Windows 8. Called them this after noon and getting a new version updated to work with Windows 7 and 8 with new powders updated through January of this year for $21 upgrade charge.
For those that do not know about Quickloads it is an very powerful and remarkable accurate program for predicting internal ballistics for any cartridge you can think of. If the cartridge is not in the database it allows you to create your own wildcat and see calculated results.
While not a substitute for reloading manuals and online data from powder manufactures it is another tool that is very interesting to use. http://www.neconos.com/details3.htm
