955 fps!!


10d nail with 10 Gauge wad at 300 psi. First ProChrono shot.

Home made light kit. I used bulbs and sockets salvaged from a microwave.

Notice the tape over the light slits.

That's snorting right along. :)

Your light kit looks far sturdier than the one which came with my F1, good job.

Out of curiosity though, have you tried a shot outside without the light kit?

Thanks.


Note that the light kit just sits on the plywood and I can slide adjust it if necessary. I can use a spring clamp or a C clamp if necessary.

All shots are inside the garage.


I just shot a marble hot glued to a 10 gauge wad at 1044 fps using 300 psi. First time to break 1,000 fps!

The marble weighs much less than a 10d nail.

I am quite satisfied with the Trom-Boyn Oak piston.

As I clean it up it looks better and better.

Note too that the barrel is friction fitted to the T with no apparent problem.

I have been thinking about a lock mechanism for just in case, and would appreciate your inputs.

Something along the line of a plastic belt clip that engages from both sides comes to mind. The kind that you squeeze to separate.

That's impressive... Why not try 500 psi? Or is that gun not. Rated for it...

I have had it up to 550 psi, no problem.

I am developing nail darts and 300 psi is enough for that.


I am curious if the gun can break the SOS so I may go to 550 psi sooner rather than later.
