Whatever. However he said his whitetails can go up to 200 lb. And a whitetail IMO is harder to anchor than an elk. A whitetail seems to be just a tougher animal despites its diminutive size compared to an elk. And by the way, I like the old stuff too. I have Winchesters in .405 and 4 or 5 .45-70s. But your question just goes back to my quote. Why do you always insist on good enough when there are better things out there. You just keep on insisting we should all use either PRBs or some other kind of all lead bullet in our MLs. And that jacketed saboted bullets have no place in ML.
So like I said earlier, if you want to use so-so bullets, that yes, will get the job done, then be my guest. We, who experiment with different loads, bullets, barrels, etc will use what we think is best to kill an animal, regardless of size, in a quick, clean and ethical manner which will not put a stain on the reputation of muzzleloading.
