IMO Muley , being PC has nothing really to do with it considering the rifle being chosen .
but thats neither here nor there as if we want to go that rough , then we have to say yes its PC as the TC rifle was marketed for a conical and in a time when conical were being used for hunting . So I guess it all depends on how fine a line one wants to hold .
As many folks here know , I use both RB and conical in my slow twist flintlock . What I chose is dictated by what and where im hunting . Most times if im hunting on the canyon rim for bull elk , then I chose a 435 grain 54 cal Bernard Minnie. Not because the RB wont do the job but because im hunting Bulls in the Rutt , at very close range , in an area where the difference between going 100 yards and going 50 yards can make the difference between getting them out and needing a Knife and fork . They 435 grain does a lot more damage , carries a lot more energy and at very close range often times puts even a big bull that’s all worked up , if not right down , within just a few yards .
The rest of the time I mostly use RB as does my wife in her 50 cal ..
So is the type of conical I use PC for my rifle , I would give a hands down NO on that one . But is it accurate out to around 75-100 yards for hunting and do I use them . Yep I do in my 1-70 hand forged barrel
