I bought a new Witness Hunter 10 mm a few months ago.  Haven't shot it a lot: maybe 150 rounds?  I think I may have had one malfunction, can't remember specifically.  Off the cruddy rests at my range (2x4 frames with a piece of carpet stapled over the top) my second five shots after taking delivery went into 2" at 25 yards (with four in about 1.25").  I am a complete spaz so I'd bet it could easily group in one inch from a Ransom Rest.

With Nosler 200 grain over 9.2 grains Blue Dot I see 1140 fps; over 8.2 grains Blue Dot 1045 fps, over 7.7 grains Longshot 1150 fps.  Same bullet over 5.6 grains Universal not chronoed yet but looks promising for accuracy and is a snooze to shoot.  All these function fine with the heaviest spring in the kit.

Trigger could be a little lighter, but breaks cleanly enough.  Overall, very happy with it.  Biggest complaint is that the locking case is huge but doesn't ship with any extra mags.  Why is the case so big?

*No explanation necessary, but it's actually .429, which is way less than .430.

Obviously the 10 mm is second best (or more like third best) to the .43 Magnum*.  So?  The same point would be true: a pencil-thin, deep wound may be fatal eventually, but it probably won't hurt enough to distract the animal from coming at you fast.  OTOH, a decent JHP disrupts more tissue near the surface, where the pain receptors are actually located, and will be more likely to divert the animal's attention, letting you shoot again.

There's just no way I'm going to carry my 7.5" Redhawk while hiking or mountain biking.  Too big and heavy.  My 10 mm carries concealed and comfortably in a fanny pack holster.  The choice is not between the .44 and the 10 mm.  It's between the 10 mm and nothing.  I hope the 10 mm is better than nothing.

*Semi-jokingly used to deflect .45 Colt guys who can't resist pointing out that the .44 isn't really .44".

I decided to load mags to fire a string of XTP, XTP, lead, XTP, XTP, lead, (XTP, lead, lead) x whatever fits.  I figured, in the very unlikely event that I need to shoot an animal AND actually get the gun out in time, alternating distracting hollow points and deeply penetrating flatpoints would be the way to go.

That JJHack is either a BSer of the highest caliber or someone who should be taken very seriously.  To me, what he writes sounds very believable.
