There's no need to make shooting complicated - it's not.
If you don't think shooting is complicated, it's because you don't fully understand the subject.
If I were to show you a rock you'd say so what its a rock. If I showed the same rock to Neil DeGrasse he could trace the elements back to the big bang and the development of our solar system.
Shooting is very much the same way and Youtubers have a challenge that the audience is much like yourself, they want a short simple answer to what is probably a far more complicated subject. Most of the audience could not comprehend the facts even if the youtuber knew about it and tried to explain it. For this reason few people ever try.
You yourself have made many suggestions that illustrate how much you don't understand, and you don't even see what you missed. An example comes to mind when you degrade the value of 223 for PRS but advocate for 22BR instead. What you obviously don't understand is the subtleties of chambering reamer design as the characteristics of the neck and throat of a 22BR can be applied to the 223. Once that is done, the
only difference is increased bolt thrust, about 50 feet per second and more recoil with the 22BR.
Oh and reamer manufacturing tolerances, barrel chambering techniques that result in over diameter free bore... OMG... people will get lost long before they understand this is all critical to the end result. And how Erik Cortina has such a tight diameter free bore that it does not matter how much jump or runout the has... not that anyone reading this post even knows what diameter free bore they have and what works for Erik wont work for your sloppy throat. Then we can get into how Sierra bullets are smaller in diameter compared to Berger and how that throat diameter can only be idealized for one or the other and not both.
And when Erik tells us all to FL resize every time, he doesn't mention that his reamer is made to match his sizing die, or that his sizing die was made to match his reamer.... He conveniently leaves that part out as guys try to take his "simple" advice and try to win the F Class nationals with a factory chamber and store bought dies.
Try explaining this difference in a YouTube video. You'll get 200 views in 6 months, but Frank can drone on about what part of your finger should contact the trigger and mystify such a minor point while dummies watch such irrelevance with fascination. Why.... because its simple.
