If you fell you have to shoot that far then get a Sharps or a Remington rolling block. With the sights available on a traditional ML shots past 150. Are pretty iffy. Tang sights? Hooded front sights? What about laser range finders? Cause your gonna need one. I have also hunted quite a bit with BPCRs and even with a nicely accurate such rifle in 45-100 or such shooting from cross sticks its not that hard to miss even an elk at extended ranges. I have done if from a simple bobble or a friend of mine years ago missed a BIG YNP bull at 425 from simple range estimation errors and we are and at the time were well experienced. But as the range gets extended the trajectory gets very steep and when there is nothing but the animal out there to give a hint as to range its very easy to goof the shot simply through a trick of lighting or color. And I am pretty well experienced in BPCR at ranges to at least 600 yards aand have shot “gong“ matches past 1000. Also I have, for example, hunted Antelope with a tradition ML successfully for decades. Where I often hunt, and I am a stalker, I don’t sit in a blind by some trail, there is often no cover other than rolling prairie and maybe some hills and grass. You gotta know how to hunt. And I hunt public land almost exclusively. Have I made a few 150 yard shots on animals, sure, but at 72 my eyes are not what they were when I was in my 20s and 30s. I have made successful shots from standing on deer, with a FL, no choice I prefer sitting out prone when shooting animals to 100 or more at times. My shooting eye got so bad that I had to stop hunting with open sights for a few years and went to a brass suppository rifle with a scope. But they fixed my eye, pretty much, and I shot a WT doe at a about 20 yards in a creek bottom with my swivel breech. Yeah I walked up on them and got a shot. So I have shot probably 100 various deer, Antelope and Elk with a round ball. They almost never stay in I suspect that I could count the ones that don‘t pass through on one hand and tow of these were pistol shot, actually I thing it was 6 total. For exmaple, back when my folks still had some land in Montana I was hunting on the school lease and say an antelope buck bedded in a coolie (thats a draw or what ever for Eastern types) so I sneak down there knowing he must be hurt, he gets up at maybe 20-25 yards and I shoot him with a 6” barreled FL pistol 50 cal 45 gr os FFF. It passed through and put up such a dirt plume that I thought I had somehow missed. He took a couple of steps and piled. He had been shot throught the mouth from the side by some modern and was pretty messed up. I shot another dying but still alive mule deer buck at an angle from shoulder to diaphragm missing the big bones and was at the off side hide at the diaphragm. This little pistol at 800 fps, yeah I had a Chronograph over 40 years ago, in baffle board tests, would give about the same penetration at 25 yards as my rifles a 50 and 54, would at 175-200. And the Maxi-ball, the reason for the baffle board tests, did about 30% more. But since the RB at normal ML ranges almost always passed through what was the point of the Maxi-Ball? It was to appeal to people who did not know any better. AND from various reports it was a very poor killer and resulted in deer at least escaping and in one case the guy killed the deer the NEXT year with a bullet track though its lungs. I have a friend in Canada who, along with his brother gave up on conicals altogether. And who watched another hunter blow him do a one shot kill in a moose at 175 yards with a 54 RB. No stern chase required. Finally the risk part involves two factors, first the early rash of T_C “Hawkens” that failed when using the Maxi (may have been one with the RB) and there were a number of them and people were hurt. They were getting barrels from the wrong source. And reports of friends hunting with or meeting hunters in the field with the Maxi partly protruding from the muzzle since they did not stay put. The three of them were using the things and one had this problem. Same guys that finally gave them up for the RB. The US military was very familiar with this phenomenon and this, I believe, is why proofing of rifle muskets involved a Minie ball spaced off the powder. They never could make them work for a cavalry carbine since even the smoothbores would unload themselves when loaded with paper cartridges when slung.
For reference see:
”A Hunters Wandering In Africa” by Selous
“The Sporting Rifle and It’s Projectiles” by Forsythe
“Wild Beasts and Their Ways“ and “With Rifle and Hound In Ceylon” by Sir Samuel Baker
“The Gun and Its Development” 1896 by W.W. Greener. He talks of MLs shooting conicals not killing as well.
”Firearms of the American West 1803-1865” Garavaglia and Worman
And I almost forgot.
”Pondoro” by John Taylor. Specifically the “More Elephant Stories“ chapter.
”The Oregon Trail” by Francis Parkman where his guide (whose name I could not spell without digging out the book) kills two buffalo in two shots at 175 yards. Remember the Buffalo hunters of the 1870s thought that 2-3 shots per animal with more powerful brass suppository guns was a good average. But they would intentionally gut shoot some to keep them from running.
Now having hunted with a wide variety of firearms and quite a bit with round balls, some few with a couple of American military service rifles, several different BPCR calibers and case lengths and other brass suppository types from pretty anemic to pretty powerful and having guided hunters for Elk and deer. I will tell you this SHOT PLACEMENT trumps power. Penetration? As Forsythe states it only need be ”adequate” since in most cases on deer sized animals a 50-54-58-67 pure lead RB give about 30” of penetration what’s the problem? They will kill, from both historical and contemporary experience a wide range of critters efficiently at ranges exceeding many shooters capability with traditional sights. Will a PROPERLY DESIGNED conical or cylindrical work? Sure. Shot critters with them, just not in a ML.
Finally if you miff the shot with ANYTHING or go for a “Texas Heart Shot” as some might call it, you will have problems no matter what you are shooting.
