As for 1899's question about quick shocks/prefragmented, it really isn't all that great. It has Stinger like ballistics (light bullet, quick for .22LR) and as stated fragments into 3 portions on impact, unfortunately this makes it an incredible maimer rather than killer in my experience. Gophers almost always made it down the hold without a hit to the neck and above, and with lots of blood trace. Flashy, but not recommended.
Now Velocitors I recommend 110%, they are THE best .22LR ound there is. They are the only round I shoot gophers with anymore. I did a test at our place in Alberta where I shot large thick plastic jugs full of water lined up and recovered the bullets. Most .22LR "hollow points" didn't even expand at all and overpenetrated greatly. However, the Velocitor showed textbook mushrooming from its "Gold Dot Hollow Point" (I laugh at calling it a gold dot, but it is a nicely swagged and plated piece of lead

) and stopped in the first jug, just damaging the backside of it (would be about a 8-9" wound cavity, but this is water we're talking).
Anyhow, to make a long story short, Velocitors are very effective on
small varmints. Wouldn't use one on a coyote, for that I consider .221 fireball minimum. But for gophers, it really thumps them and you can see them take the hit hard, it drops a lot of energy in them unlike the cheap HP's or solids.
As well, Velocitors are very consistent and accurate, I shot a 2.27" 5 shot 200 yard group (that's almost MOA with a .22 at 200 yards!) with them last year in my Kimber. Eagleye beat the group, but not sure what ammo he was using.
