Danny, all you need to know is the exact distance, barometric data, temperature etc plus MV at both distances and it is some simple math, alternatively there are some nice apps on-line such as this one http://www.jbmballistics.com/cgi-bin/jbmbcv-5.1.cgi
I do have a spreadsheet that does the modelling however I seem to have broken it at present so I need to wave it at Tim when he gets back.

Ha cool thanks mate. I'm hoping the wife is taking my rather unsubtle hints about my Xmas prezzie of choice being one of your accoustic chrono's
Re: G1 / G7 Data
