Some time back several members took up an offer to obtain a copy of the excellent free internal ballistic calculator of this name. That version no longer works, having been superseded by the current version, which looks essentially the same, but with some changes and updates. It is supported by a user group which you can join.

It took an hour using fast broadband to download the archive, which then needed to be unpacked and installed. If any members would like a copy of the current version (Windows & Linux only), please contact the club. We can then distribute copies at a monthly meeting.

For those unfamiliar with this software, it very accurately predicts pressures and expected velocities. Virtually every available projectile, powder and cartridge is listed, with the exception of some less popular ADI powders. ADI does have information on equivalent powders in other brands which I have used successfully. Keeping safe is a big plus when using this program, as it warns whenever an overload or unsuitable powder is trialed. Selecting suitable powders and starting loads for any cartridge will also save time, money, frustration and a potential disastrous overload. I am quite simply amazed that such a comprehensive useful piece of software is actually free!
