Been killing critters with tipped bullets for a long time. The ones with white tips. Killed a bunch with Core-Lokts and others before that. Killed a few at longer ranges also with a tipped bullet. So Don, keep your mouth shut about tipped bullets. mtmuleyOh. But if the tip's kill, why is the rest of the bullet needed? I do suspect you might be right but without the rest of the bullet, how fast would you have to drive the tip to get it to penetrate deep enough to actually kill something other than a fly? In my opinion, other than helping a monolithic bullet point open or a varmint bullet explode the only reason for plastic tip's is a sales point! I don't know how old you are but years ago Speer brought out the Mag Tip bullet. To sell it they showed a high speed photo of a bullet soon after leaving the barrel, it had melted off to the jacket, looked much like a Remington Core Lock!
Just wondering, do you suspect a bullet with a plastic tip compared to a tip, say a core lock, will kill any different at some greatly extended range, say 1000 yds, than the core lock assuming same MV and same bullet placement? I don't!
