I noticed Wolf is available loaded with 55-grain hollowpoint bullets.  What is the story on these?  I mean, I've already heard about how the regular Wolf FMJ doesn't fragment, but I haven't heard anything about how the HP does.  Is it like a varmint load that explodes when it hits a gnat, or is it something more generally useful?

EDIT:  Now that I look closer, I see there is also a 62-grain HP loading.  Same question still holds. . .  Is it good for anything?

Not worth it.  The FMJ feeds better in my gun than the HP to start with.  Also, the jacket on the Wolf HP is very thick.  It will not fragment.  Do not use the HP as defensive ammo.
