"We need to face the facts. Roundballs are awesome but conicals can outperform them."
only on paper and in some peoples minds, plink is correct as are many professional guides and longtime hunters who have put aside the modern style bullets in favor of the PRB,a great many of them found rather poor results with conicals, now the closer you get to modern bulets in material and design you may have an edge but probably not due to lesser velocities but then you are very close to not really ML hunting as well.I know one fellow who lost or missed a couple of deer with PRB so he tried a conical he killed a deer that season....this proves nothing and is the type of evidence that most try to use as data for the conicals being better. it is much like the Bumblebee being unable to fly.
"There is no doubt in my mind that you guys have amazing luck with PRB.'
luck has nothing to do with it, a ball thru the lungs at typical ML ranges/open sights will take that Elk you show as well as the conical, this can be documented over and over for over 200 years,
the use of a conical is generaly as a result of not having faith in the PRB, not in the NEED to use a conical, the conicals are leagal in most states and many choose them but do not try to make a case for the NEED to use them, and do not try to place the ones of modern design into the traditonal projectuile catagory, even their manufactures will not go that far, The use of PRB over modern conicals is one of several lines between traditional ML hunting and a mix of the old and new that some will not cross for whatever their reasons, which is fine that is their right, but along with the right goes a responsibility to refer to them as what they are and not try to spin, wiggle or squeeze them into the realm of traditional gear.Enjoy your hunting with whatever you chose to put down the bore.
