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.
