rkba2nd,
You are correct, but I think people need to look critically at any hunting video.  The deer shot was not a large Canadian deer but a smaller Georgia doe.  The shot was at close range and the deer wasn't excited.  In those situations, the 357 PCP apparently was successful.   
My thoughts are that in the hands of a serious, competent hunter who can accurately shoot and carefully takes his shots, smaller (or less powerful) guns can be used successfully.  Those are a lot of caveats.  From the limited amount that I have seen, shot placement and having an unexcited animal are most important in one shot kills

While I do not want more laws and rules, I do like (at least parts of) the German model (as I understand it) that hunters take hunting courses to learn about hunting & gun safety and then need to pass a competency course.  What I have read and heard is that German hunters are fairly knowledgeable and respect the game they hunt.

This type of proof was also mandatory when I was hunting out of state in Colorado. My hunters certificate had to be included for their review when buying my license and my tags.

Yes and I was born in 1951. In California one just had to use their last Hunting License. When Colorado changed their Law my original Safety Certificate from back when I was 10 was no where to be found. So I had to go take the test all over again.

Born in 1943 so I hope not. I was taught to hunt and safely handle firearms by my grandfather.

yamoon  Most of us were taught by our father, grandfather, or in my case a neighbor mentor, my father having just returned from years of war in the Pacific, and saw enough killing. Times have changed, and I would not send my son or grandson into the outdoors during hunting season on public land without the knowledge that others have at least a rudimentary understanding of basic safety protocols and and awareness of pertinent laws pertaining to the use of firearms and hunting related laws in their state of residence. Rural Kansas, and now even the rocky Mountains of the mountain states have much much more in common regarding the number of hunters afield during hunting seasons. There are those that reside in large cities and have never seen a deer, or handled a firearm of any persuasion, and I would shudder to think of them out in the same area as my son or grandson, without at least a bare minimum of instruction. The good old days are not quite so good anymore in this respect at least.

This post has moved away from the original question, but it is good to have these conversations. I hunt deer every year, last year COVID-19 ruined my deer season. I have noticed there seems to be fewer hunters each year. Here is an excerpt from Kansas Wildlife and Parks harvest report.
total deer permits sold in Kansas for the 2018-19 deer season was 179,247 (Fig. 1), which is a decline of 1.85% from 2017-18 and 7.00% below the five-year average. This is the fourth year in a row that deer permit sales have declined. Most of the declines are in resident over-the- counter permits. The largest declines were in Whitetail Any Season General Resident, Whitetail Any Season Landowner/Tenant, and Whitetail Any Season Youth. Non-resident permit sales have been steady since most non-resident permits are limited availability with quotas, but slight variation occurs with Hunt-Own-Land permits.
I hope to pass on everything I have learned to my 13 year old nephew as soon as he can legally hunt. I am afraid hunting is a doomed sport.

yamoon  I can't speak for the state of Iowa, but Colorado for example has managed to complicate the equation by offering multiple hunting seasons, beginning in late August, and continuing through January,  which puts game under much longer periods of stress and disrupts their normal behavior. What it really boils down to, is money. I would guess that hunter numbers have declined in most states, due, at least in part to the constant cry against hunting in general, and more and more people are gravitating to large urban areas for jobs, schools, etc ,etc. In Colorado, another blow to the Game and Fish department, was combining that department with State Parks, to gain access to game department funds. Again, de-emphasizing the game department. There is still a very large portion of Colorado in(or should be) in the PUBLIC/PEOPLES domain. National Forests, BLM, State lands and wildlife areas etc, many of which are being sold to oil companies, mining interests, power companies, government agencies, developers large corporate entities(read ski slopes) and more access roads to support the above. It will never end as long as large population corridors(cities)dictate policy, and attitudes don't change.            I really have gone off on a tangent, guess I just had to blow off a little steam, and I don't even(by choice) hunt any more.
