Besides the Winchester PDX1 (which is no longer made), I don't question these velocity figures. From a ~2 inch barrel, proper .22 Mag can get 1100 to 1150 fps which would work out to a whopping 110-120 ft/lbs. Compare that to about 80-85 ft/lbs with proper .22 hyper velocity and the question becomes does the slight extra power of .22 Mag make enough of a difference to justify using it in a short barrel?Here are some stats compiled in an NRA test, which include penetration -- just to correlate with those provided by NAA...

Clearly in the shortest barrels NAA makes, it's not because the velocity jump isn't enough. Add another inch on the barrel and you effectively double the gain in energy vs the gain in energy with the 1 inch barrel. More is nicer, but is 30-40 more ft/lbs worth the extra blast, recoil, decreased reliability, cylinder capacity, increased ammo cost, difficultly of obtaining proper ammo during a panic, and/or outright lack of being able to buy any ammo during a panic or shortage?
If someone has a .22 Mag rifle and has ammo stocked, it may well be a good choice for them to also own a small .22 Mag revolver. For myself, I have no use for .22 Mag in a rifle and I reload .32, so it's not for me. I prefer an 8 shot .22 LR snub and I'll load it with whatever 40 gr bullet gets the highest velocity. Even if it's stuff like Velocity that costs $8 for 50 rds, that's still half price of the Speer or Hornady .22 Mag short barrel stuff.
