Dukkillr...
While I can understand your position, I am also trying to understand Jamal's. He has a preference for air rifles and is apparently just getting into powder guns. Evidently he doesn't like heavy recoil for whatever reason..small stature, age, shoulder problems etc..so most of us just tried to help..
From experience I can tell you that my H&R 12 ga slug hurler worked for many as my only deer gun..but being 71 now..and with a damaged shoulder, a 20 ga would not be out of order...LOL
Fortunately, 2 years ago my home county "saw the light" and now permits rifles..so a Marlin 336C..30/30 fills the bill.
While I can agree with your striving for "clean kills"..I must admit that I do hunt with "Novelty" guns..such as single shot rifles...for the same reasons that some archery hunt and some use flintlock smokepoles !
I also hunt for the altruistic reasons..I enjoy the planning, preparation and execution of the hunt..the selecting guns and ammo..the walk in the woods & fields, and the game that I simply observe, and then "pass up"..
If i were just hunting for the meat..I would be forced to laugh at myself ! considering the cost of licenses, guns, ammo, clothing, studying, planning and time spent...while often coming home empty handed....but that is just my $.02...
With what I spend for those things, I could buy great quantities of very expensive meats !...LOL ...And do more profitable things instead ...
...But hey !..There's room for all of us ..LOL
