For myself I have always consider a PB to be nothing more than an "Extended Round Ball" - I believe when PB introduced the 'copper clad' PB they did try to simulate a copper/lead hunting bullet - but the copper was really a very then bonded layer of copper and did very little to 'toughen' the bullet. PB has continued to try to improve the strength of the bullet with different improvements - but it still lags far behind many other bullets on the market.

I will say this this - if you shoot a PB as you might a PRB - you could be very successful with them. But how many people 'today' even know the limitations of a PRB? Certainly not the new people just buying an inline and going hunting.
