My state doesnt have a straight wall season, we have a "regular season" in which any implement may be used, we have a muzzleloader season, and we have a bow season in which (as of a few years ago) both vertical and crossbows may be used. The rationale I am very familiar with having been involved in some of these season-setting processes, is that people want the longest season possible, the state wants to kill the number of deer they think is necessary to achieve management goals, and there is a long-term decline in hunter participation in this region (verified by license sales, that is real) so they want to make access to hunting as easy as possible for new hunters at the same time. The combination of seasons and allowed implements is the best way they have found to be able to do all of those things, even though there are people who bitterly complain about this from a variety of perspectives. We dont have any areas in the state where firearms are restricted in any way except inside city limits in a few of our cities where firearms discharge is prohibited except in self-defense.
None of the neighboring states have a staight wall season either. A couple states south of me there is a shotgun-only season which is their firearms season. As an outsider everything I have heard and read on the subject is that shotgun and straight-wall seasons are a solution to hunting in much more densely developed areas and areas that have mostly much smaller parcels of land, and/or more people who want to hunt. So both density of development around hunting areas and density of hunters, is the concern in limiting the effective range of implements from a safety standpoint. Everything I have read on that subject points to shotguns and straight-wall cartridges as having lesser range before hitting the ground, which is the main factor. So as far as I always knew that WAS the definitive answer: we have these seasons to allow the longest time to hunt, while still keeping efficacy low enough to stay below harvest maximums, efficacy high enough to achieve enough of a harvest to reach management goals, and maintain as much safety as possible in suburban and semi-rural areas.
regarding some comments I saw in this thread earlier: I did some reading and found the PA richochet study mentioned has a lot of detractors who felt that the study had numerous flaws that render its conclusions un-useable. Here is one example I found on a quick google search
(link). One reason I saw that people discounted it was that they apparently didnt actually do any testing, it was all based on a computer model; the other reason being that they did not account for the dramatically flatter trajectory of a necked rifle cartridge and therefore the much greater distance it will travel when fired horizontally before hitting the ground when a target is missed, instead focusing only on richochet from a flat and hard surface (which is a extreme rarity in woods and fields ime).
So what I can find leads me to believe that the reasons for a straightwall season (rightly or wrongly) are the same as they have been explained to me every time in the past--to allow a combination of seasons providing the longest time to hunt, while still keeping efficacy low enough to stay below harvest maximums, efficacy high enough to achieve enough of a harvest to reach management goals, while maintaining as much safety as possible in suburban and semi-rural areas.
Where I am lost is the new arkansas regulation. Every reg I've seen from my own states and other states fish and wildlife dept gives the
reason for a change...the
AR info I found (link) doesnt provide any rationale whatsoever, nor does it illustrate any goal, and seems kind of contradictory to allow repeating cartridge rifles, but explicitly NOT allow shotgun slugs. Maybe it makes sense by some rationale? ...but no such rationale was even hinted at. If nothing else, allowing repeating cartridge rifles while not allowing shotgun slugs seems to toss any nuanced formula around harvest rate vs hunter efficacy as a rationale for the regulation out the window.
