I love the Stingers.
Originally, the Stingers were were marketed to be compatible in any .22 LR firearm. We know there are some shorter chambers aka match chambers, that the longer Stinger case may not fully chamber. That would be problematic. A carbon ring in the chamber ahead of a LR cartridge could also hinder full chambering of a Stinger. But so could a standard .22LR cartridge after a carbon build up in a chamber that's only seen .22 short cartridges. Such a ring is easily cleaned out.
I will continue to use Stingers in appropriate chambers and I will continue to experience good results. To this day, when I experience a .22 pistol with function problems, I still often use Stingers or other Hyper Velocity rounds to help wring out the problems. I do insert a Stinger into the chamber, making sure the chamber is cut long enough for Stingers.
And, there are also other .22 Hyper Velocity cartridges by other manufacturers, with similar ballistics, but with a standard length case. I am pleased with them, too.
For the folks who proclaim Stingers to be "garbage", that is not my opinion. Just like with many other brands of ammo, some work better than others in some firearms. Using Stingers for varmint control at extended .22 rimfire distances, I've found them to be very effective.
