Reply To: Range Cards vs Ballistic Calculators
That’s good info. I also use a spreadsheet and trajectory programs to create range cards. I much prefer to have the information at hand rather than using my calculator or iphone.
When I realized that I would need different cards depending on targets or environmental conditions, I started using a data book while shooting. I try to anticipate what targets/conditions I may encounter at upcoming shoots and prepare pages to go into my data book. I fastened the “book” to my shooting mat so that it is right there for the prone or sitting shots. The pages are in sheet protectors and I use tabbed dividers for quick access. I recently replaced the cardboard (got soggy in wet weather) dividers with thin Kydex dividers.
I add or subtract pages as my needs change.
