Looking for advice here chaps. Went in gun cabinate today to wipe down and fire a few pellets through my b&m bullpup daystate ph6 to find the gun was empty so seal gone or slow leak most likely. Tried filling and heared a hiss near block. Cocked gun and it took air but not showing gun pressure on divers tank reg. Gauge working when filling and showing tank pressure. Now i was to shit to carry on filling the gun as not knowing the pressure worred me. Gun cocked and dry fired so air was enough to stay in gun so guessing there must be at least 100bar to keep the guns fill valve closed. Any idears as i dont have a hand pump as back up as that could have been a safer way to check the gun pressure than trying the tank again. And a springer guy mostly so not as clued up on tank reg problems as others on here. Just dont want to risk a bad accident over filling the gun as you can understand. And ideas or answers id be most greatful chris
