Corbin Information Discs and Perry Systems Exbal

[Ronin]

Been having a bit of a clean up of the office 

found a bundle of CD Rom discs from Corbin (bullet swaging, twist rate calc, bullet design, paper patch calc etc etc) from when I dabbled in bullet making - a real rabbit hole ,,,,

and two discs for the (then) excellent Perry Systems Ex Bal system which was at the time cutting edge - you could even place the darn thing on a PDA and carry it about - go figure !

 

The Corbin discs are circa 1998 I think 

 

 Exbal - circa 2001? 
 

If anyone is genuinely interested in these pieces of ballistic history I’ll send them to you gratis
