From my perspective, the introduction of "hollow pointed" rifled slugs was a triumph of "popular marketing" over terminal performance.
I don't know... But I kind of disagree here. See, the reasons Shotguns are so wonderful is the versatility granted by picking the right tool for the job... and in this case the tools are your shell selection.
The HP design by Winchester has it's purpose... and saying that it's less desirable than the others simply for the lack of penetration is only true if maximum penetration is the purpose.
Winchester clearly states the purpose right on the box.
"DEER". And for those that are illiterate, it clearly shows the images of a white tail deer. Hardened penetrators are less ideal for this game... Thin skinned and light boned, like your average Snowflake, you want more shock effect into the target. The HP design causes a lot of deformation, which as we know, helps cause tissue disrupting shock. It really does do a lot of damage into soft meat target... Making it the ideal choice for White Tail - or for Defensive use.
The other slugs... Are of course better suited for Dangerous Game where that max penetration is ideal. And what makes them ideal for that is the same reasons it's less ideal than the Super X slug. I've seen a lot of well placed shots from high powered rifles that allowed the game animal to run for a half mile... Where similar shots with rounds like a 150 grain .30-30 just crush the target.
