Questor;
I think you are right on the money with this question. I would agree with you that the 41 mag may well be the pratical optimum for almost all deer type hunting in cover. Personally, I like the 44 Mag and am seriously thinking about Gary Reeders 41 GNR.
That being said I am going to throw a little curve. I am from the state of Kansas. We have no specific handgun season, any hunting that you do with a hundgun is done during the rifle season. (In Kansas, rifle season is very bad because if you hold a tag of anykind you can go to the field and hunt with it during those 13 days, plus every game species season is at full throttle except coyote and turkey. This is very bad because hunter traffic gets exceptionally high). Add to that the fact that the western 2/3 of the state is tree barren. To hunt with a handgun in this enviroment, you have to adapt bowhunting type skills to their ultimate level. The things you have to deal with here is almost always no rut, bad moon phases and deer at the peak of wearniess. You have to be very sure of previous scouting and ready for your shot(sometimes it takes 5 days or more for the shot -sometimes the shot never materializes). Many times the shot will be over the 100 yd mark, that takes a specialty pistol, a good flat shooting cartridge and A LOT OF PRATICE!! Anyone can take a big buck with a bow and arrow during the rut - that's a no brainer!! Take a big deer with a handgun or a blockpowder handgun, You have my attention and respect. I know that you know how to hunt deer when you can do this!!!
I will admit to you that I get greater satisfaction taking deer with my 44 Mag 4" than any other gun. It's up close personal and alot of fun.
NOTHING BEATS HANDGUN HUNTING!!
