Went to fill up my SCUBA tank this afternoon, it seems there have been a few accidents with old/damaaged tanks being refilled. SCUBA tanks now need to be certified every 12 months, regardless of their intended use. We used to get away with filling them for PCP use, but no more. Tried to talk...

Where do people source the SCUBA bottle carrying harness?

Why could this be used for pellets? I've had other rifles using a probe pin and they worked fine.

A sequential process I can understand. Nicely done.

A friend has a carbon sleeved .260 first few shots on point, but things becomes more random. Takes ages for the barrel to cool down. Not sure this would be the case with an air rifle as there is no chemical explosion to heat the barrel, not comparable to pellet friction. Do we have an update...

Was running reg at 110bar, now at 125 bar approx, 22cal shooting JSB exact Jumbo Heavy. Not sure how to play with reg washers. Sounds like I should by a HUMA high pressure reg and a Sekhmet digital gauge. will see if reducing the valve stopper distance has any effect in the refresh cycle first.

Why is this so? Why doesn't the reg allow immediate recharging. Are all regulators slow to respond in this way?

Ta, Good too hear someone else has the issue. Was concerned I had done something to the new valve seat during installation of the PP.

It is similar to one I have seen that does work.

While doing some testing to resolve differences in velocity, I noticed full recharge to reg pressure was not instantaneous. I've found consistency improves if I wait 5 seconds, watching the gauge after a shot it creeps back to full reg pressure. I didn't notice this before I installed the FX...

Maybe it matured while locked away!

I've put 2,000 .22cal pellets through my Impact and recently installed a power plenum. Still holding together as new. I did have a Hatsan that caused some concern when the grub screw holding the action came loose. Sent it back to retailer as unsafe. It was the only one which could shoot H&N...

A small question if I may. What defines a slug? Calibre, weight, shape! My first springer air rifle many years ago, in Australia, was commonly referred to as a slug gun (.177). My FX Impact is happy shooting JSB 25.39gr and Cometta exacy jumbo monster pellets 25.4gr, through a X twist...

Just a thought, instead of sand paper and dowel/rod. How about bronze brush and cleaning rod to increase the ID...

Installed the PP in my FX Impact X, a couple of days ago. Both vids have a couple of tib bits missing, but having watched them both it was easy enough to avoid making a critcal mistake. I didn't notice before I installed the PP, that it is best to wait 5-8 seconds between shots to allow the...

Good point, I come here to read what others are doing and learn. A tuning forum which addresses different brands makes sense. 

Looking forward to getting a PP, I have one on order from our Australian distributor. I have ave a bunch of H&N Rabbit Magnum II 25gr that will not shoot in the FX Impact. I'm guessing they need more punch to make them shoot, they knocked rabbits for a six in the Hatsan 44 unregulated...

Below are the setting and results from testing range of setting on myFX impact, with a .25 cal ver 1 barrel, 33.95 JSB Exact King Heavy pellets, 125 bar. I notate ring is one complete rotation of the valve adjuster. The extremely low velocity on second set results from closing the valve...

Must admit, didn't even consider altering the unit.

Someone may have already covered this but here goes. The adjuster has some groves to show changes went it is rotated. My eyes find it very hard to read as things are dark in that area of gun. Remove the adjustment nut/cover and paint each grove with whiteout or white paint. Makes it much...
