I do the same and because I use IMR powders, or RL16, I keep track of the temperature and weather effects on my loads, also on my dope sheets.As I only shoot at known distances - JBM initially - and my own notes/drop chart, after shooting a new load. I keep a dope sheet for most of the ranges where I shoot, as target distances do vary.
Thanks men for all the replies ,now I have to check them out.
Yep..still the best...just dont upgade your phone.
A club member reported last week, that his Strelok updated itself. ah..those magic fairy phones. Odd though.Chairgun Elite, Since I had to get a new phone and lost Strelok. It's pretty close UI and performance wise.
Unfortunately JBM isn't available as an app for a cell phone.JBM - Calculations - Trajectory (Simplified)
