The where it's leaking from is my question. I have not been In the rifle, just witnessed the pressure guages going down together. I have never used a leak tester or narrowed down the source.
Get the kit for the Arca Swiss Rail mount. The Rail mount creates a secure mount for repeatability. If you set up the original bog clamp, that could be used also.
Need help with leak on a FX Dream Tac filled to 220 half hour later gauge is at 150. Changed the bottle, both regs went down to 150 IN A Similar time period after topping off at 200. Nothing was loosened or tightened to create the leak.
