Your musing points exactly to the core. Because it is no longer so. This old calibre combination of 20-20-5,6x52R reflects hunting conditions, hunting demands and hunting interests that no longer exist, that have become museal.
They have turned almost 180°; and except for some islands at the coast, and generally the utmost north of Germany, nigh every Revier today practically is a "Hochwildrevier". It is the classical Niederwild of the 19th century that is everywhere missing (never mind the pedantic fact that roe deer also is Niederwild, and the adjacent fact of the proliferation and urbanization - maybe gentrification ;-) - of foxes too).

I can and possibly should describe the hunting foibles of yore in more poetic detail, and would have to contrast these with the hunting (and hunting goals, id est wildlife management) of today. But at the moment, my literary creativity feels a bit stifled, so you might have to wait a bit more.

I am very thankful to live under a constitution that includes the second amendment, and I wish my German friends had this protection also.

True, that indeed is an almost unique point worldwide; just like the imperial measurement system. :-) [The only other exceptions are Czechia - article 6 al. 4 of the Charter of Constitutional Rights and Freedoms, since 2021 -; and Myanmar]

But the real legal problem in this specific given context is different here in Germany, beyond such legal eccentricity. It is actually the continued underexposure of article 14 of our German constitution in the constitutional jurisprudence, and the material disregard of the Federal Constitutional Court (BVerfG) for the consequences of firearms law provisions that materially infringe upon the right to inherit.
