depending on the pressure yes.. That screw could fail and make the valve a bullet.. Generally , for applications over 1000 psi , people use several pins.. Even with a regulated drop bottle conversion , if the reg fails , the system should be able to withstand the pressure for the split second it presumably takes for the burst disc to fail... 3 pins is the norm, but others have done 2-5 with varying size screws and locations.
Our own Mr. Gary/Wyoman does it.I emulated his method and had mine drilled and tapped (2 tiny stainless 6-32 set screws) with the valve installed inside the tube.Do it top and bottom so that the set screws stay hidden when the breech and trigger assembly are installed.It is a very solid mod.

Yes, a drill press would be a good investment.I always seem to forget to buy a Harbor Freight one, but I will get one when I am in the area.I would also like to imitate Mr. Gary's/Wyoman's 13xx barrel band reinforcement.Crosman tubes are pretty soft for drilling, you know.Just look for the thickest part of the 13xx valve and drill it.If the valve cap, like the 22xx's, is thicker than the valve body, then that is where I would hit it.The top and bottom reinforcement looks much cleaner than the Disco's L/R method.
