I have hunted from treestand, groundblind, and stalked whitetail deer for most of my life with bow and arrow, we use wild game as one of our main sources of meat. Not bragging just proving a point,I have killed more deer in my life than I could ever begin to count! While I have to agree that deer are very nervouse animals, I have also put as many as 2 wooden arrows from a self bow through one from as close as 8 yards and the deer not know that he was even shot! We also raise and butcher our own cows and hogs that we kill with a .22cal. without a problem! I have knew a guy that hunted deer with nothing but a .22cal. when I was a boy! All this to say yes I agree tht it would be a challenge on the hunter, but not as impossible as some make it sound! In my opinion if you used a .50cal. or bigger found the best load and practiced stalking and shooting
{or sitting quietly in a stand} and estimating your effective range, You should have no problems. As far as ethics go, I can shoot a deer with a river cane arrow with a knapped stone point from a indian style selfbow that shoots less than 200 fps and it will expire within 30 seconds as long as
I do my part and place the arrow where it needs to go! I hope I didn't ruffle any feathers here as that was not my intension at all, I just know that what he is asking about is very possible if he does his part in preperation even though it may be alot of work and a challenge! But wait isn't that one of the reasons we use black powder in the first place insted of one of those wanna be muzzleloaders {inline} that shoot that wanna be powder {pyrodex,etc.} or even a modern cartridge guns! The challenge and the romance of yesteryear and my ancestors is the whole reason alot of us do this so I say if your up to the hard work go for it! Heck I might have to try it myself!! GOOD LUCK!!!
