DP, I hear ya. Still have many magazines from the 60's with Keith and O'Conner articles. Different times for sure.
Sort of backed into my perspective about hunting, how guns shape the way you do it. Raised a bird shooter from youth, I didn't own a rifle other than a Benjamen 312 until after I separated from the service. What hunting I did for larger game was done with a shotgun and mostly buck shot. Later on I went thru the CF rifle phase, beginning with a Model 94. Came to a fork in the road about the time I started working with rifles having serious long range capability and wound up a dedicated still hunter in the southern bottoms and swamps. As a result it has come to my attention that virtually any gun or load will work in that circumstance. Or bow, sometimes a spear if one is wacky enough.
Still do it today and have several rifles specifically sighted at 10 yards for that purpose. I do use a red dot on two of them, but no optical glass. Otherwise, it's iron sights and I don't see great difference in what rifle I use to tell the truth. Close takes a lot of variables out of the equation. My .45 has a 42" barrel and I don't find it awkward or inconvenient, cover or weather notwithstanding.
From the mid 90s when I abandoned stands and blinds, to present, the longest shot I've taken on a deer was 70 yards. The shortest was about 10', average probably around 40' and that would include something around 25-30 deer. Hogs....longest shot 38 yards, measured, shortest about 5', average close to 30 feet I'd guess. Total to date, 177 by my records, size ranging from 10-300#. Close is what I do, choice of gun driven more by circumstance that anything else. Anybody can do it if so inclined.
I'm not the least unmindful of what you said in your first post and agree with it in general terms. It is my opinion, nothing more, that attention to detail in a comprehensive sense levels the field when it comes to advantage or disadvantage normally ascribed to different tools of the hunt. When the range gets very short the differences largely evaporate.
