I'm of the age where when we learned to shoot long range, we were taught the thumb technique for yardage and then using whatever was around for wind (grass, flags, leaves, smoke etc..) and we did pretty good. Now, I find myself using bdc scopes, laser range finders, phone apps etc... and I actually have a lower percentage of on target cold bore shots than before. So, just for s&g my buddy and I went out to our range and left all the technology home. We found ourselves having a blast again, and being on target pretty well. Is anybody still using the old school techniques and if so which techniques are you using?
