I have had this tool for a long time.
It’s a Speed Fastener, Model 825, 22 cal., powder actuated driver.
It’s a high velocity gun with a thru barrel. Not the more modern style with a piston.
My question is where do I stand with this gun?
Can I use it with low power loads? Can i use it at all?
I’ve heard that you can’t even sell them.
I’m just looking for some knowlegable answers since I’m not finding much in my internet searches.
Thanks,
Chris

HV pad
Not osha approved any longer. Not sure about charges, but don't think the newer shots would work even in the higher load ranges.
I used old HV Ramsets for years. When they became illegal on jobsites, I got rid of mine by taking it apart and diposing of the parts seperately. So nothing could be retrieved and the thing ever rebuilt. I had tons of experience with them and still had a few close calls. I wouldn't want anyone not very familar whit one to ever get hurt because of their inexperience with that type tool.
Speed Fastener, Model 825, 22 cal
I use a old style "high velocity" Ram-Set I think they are almost the same.
The old style H.V. guns have no piston.
The bore diameter is .380" (.38 cal) on HV guns. Whereas new style Low velocity (LV) the bore is .300" in dia.
If you try to put a new style pin into an old style barrel It probably would not even come out. This is because the .22 blank can not build enough compression. All of the energy from the burning powder is going around the head of the nail.
I am always looking for old style pins. It seems like everbody would like to pretend the the .38 cal HV never existed.
They work great for the right application. They also are capable of fastening more types of fasteners. Threaded pins, "eye bolt" a new style gun would not be able to do this because the piston would damage the threads or the head of the pin.
However they can be very dangerous. Follow the directions Wear EYE protection. Pins and nails( fasteners) have been know to hook back and hit the user make sure the plate around the muzzle is in place. They say test the surface by hitting it with a center punch
