The hardest part used to be guessing the distance but that’s all changed with laser range finders. My son gave me one as a Christmas present and I didn’t think I need one since I go to the same area all the time. It surprised me as to how many times I have needed it. It’s also handy for learning how to read distances.
The fun part is also knowing the people I’m with can hit at ridiculously long ranges.
Try a laser ruler, the range finder’s little brother. I just got one and used it to measure my house for an insurance evaluation. Absoltely terrific and eliminated the need for a helper with a tape measure.
It still - 44 years away - pisses me off to no end that in Marine Corps Boot Camp I fired "Expert" in every pre-qual shoot....but on actual qualifying day, I hiccuped and only made Marksman; didn't even make Sharpshooter...
Pretty much the same thing a couple of years later, just before I got out (woulda been worse, but I was a short-timer) it rained and my eyeglasses got all gooed up and I actually was a Non-Qual.
