You hit the nail on the head, olfarhors. Here's info from another thread related to this one.
All of my PT-22s and PLY-22 came with and have a clear plastic with red print on it strip in the box. Not all who have these have reported this but it is a normal warning in most PT22 boxes. What it says is that hyper velocity
ammo is not supposed to be used in the PT22.
I have one 1986 produced PT-22 and the other is just a few years old. The new PLY22 is this years model.
Too high a velocity will batter the gun and it's small parts. Accelerated wear and tear of that kind will and can eventually ruin the gun.
Back in the day, many, many moons ago, I did shoot a few CCI Stingers out of my PT22 before seeing the warning (there are goood reasons to fully read the owner manual) in the box.
The slide opened too soon and some flame and burning gases (very little) came out of the ejection port. I as always was wearing my safety glasses and hearing protection and was not hurt in any way. The idea is that the slide is supposed to stay closed until the bullet leaves the barrel and pressures are at a safe level for the slide to work backward. Hyper-velocity
ammo overrides that. I am lucky worse did not happen. I was one lucky puppy.
It's like hitting one's head with a hammer. It feels so good when one stops.
ALL of the gun producers who've made and make mini-pistols in .22lrf deal with this. Most if not all mini-.22s are designed to use standard or high velocity ammo. The companies CANNOT design a mini-gun that functions with ALL .22lrf ammo. The LAWS of Physics and reality say no to that.
Boxes of appropriate ammo for the PT-22 and kin say standard pressure OR high velocity on the packaging somewhere.
The 1200 feet per second ballpark figure is what to go with for max velocity.
The old PT-22 manual states that 1220 fps was the way to go. That was as high as anyone was supposed to go. There is no +P designation for .22lrf ammo. Just standard, high velocity, and hyper-velocity. The new manual leaves something to be desired. It needs updating or clarification on the .22lrf ammo.
Correction: page7b
Scroll down the page to Taurus PT22 & PT25. Then download the manual.
It says in the manual, old one, but some things do not change over time, that is at 1280fps. Page 11 has that.
ALL of the hyper velocity ammo cannot be listed as things change to often or fast. Some loads have even gone off the market in the past. If you stay with HIGH VELOCITY or STANDARD VELOCITY written on the .22lrf boxes then you should
Folks. Do not use hypervelocity
ammo in the PT-22 please. If the manual says nothing chances are that the box which the PT-22 came in has that written somewhere on info that is in the box. All of mine did and do. I even have a new PLY-22 that has it was well. There is a piece of paper on which it was written in very fire engine red print.
If you have doubt then call Taurus Customer Service number at 1-800-327-3776 and verify this.

I have CCI Mini-Mag hollow points in my PT-22s and kin.
There is this.
