It’s interesting. The knowledge we have on these things are based on fragmentary relics, vague manuscripts, and tapestries.
Sometimes new things are discovered. He had a viewer who had been in the Balkans during the wars who said arrows would go through sand bags that AK rounds wouldn’t. He fired reproduction long bow arrows and some of them went through and penetrated a target behind. Another channel used a variety of calibers and did not get similar results.
The 7.62mm AK rounds don’t have much sectional density, that is, they are sort of short and fat. Compared to other calibers, they don’t penetrate well. I won’t favor using them on large deer or feral hogs for that reason. The much skinnier, longer, and much older 6.5mm Swedish Mauser bullet, has much more sectional density, penetrates a lot better. Compared to an AK bullet, the sectional density of an arrow would be off the charts. 😀
