Winchester/Browning offers a load that duplicates the Velocitors, and have a pretty blunt HP bullet, which adds to the mayhem, Like any rimfire ammo, it can be lot dependent. Some rifles won't like the Winchester/Browning loads, but they've done pretty well in some of my rifles. It might be worthwhile to try the W/B stuff as an alternative if you can't find the Velocitors .
I consider them to be pretty equivalent.
