Air is coming out of the small holes just below threads on tank. I’m guessing an oring inside tank . Anyone else have experience with this ? Thanks in advance

Which side is it leaking from? The side that screws into the gun or the side that your fill probe goes into?
Before doing anything, be sure it is totally empty off the rifle and bang the leaky end against your sofa or bed
really hard many times like you want to kill something, you may have debris lodged inside causing it to not seal well.
Refill the cylinder and LMK if it worked then we can proceed further.

It's your valve stem (or seat) that is leaking. Those holes are how the air gets to the transfer port when the valve is struck. You will have to degass and remove the valve to get to it.
"DO NOT strike anything with that valve, it will do nothing except maybe bugger up the threads. You may be able to "polish up" the stem/seat, or you may have to replace them. Pretty sure you can get them from Hatsan USA but it's been years since I owned mine.

I made the suggestion to whack it against the bed or sofa since its soft to dislodge any debris while not damaging the threads.
I appreciate your input. I should have said wrap it in some thick towel then bang it against something hard instead.
Thank you BTB

I only tested the end that screws in the gun so just to be safe I aired it back up to test the fill end and now I can’t find a Leak either end . Idk what’s going ha. Screwed it back into gun and will see if gauge moves over night . I’ll let y’all know , Thanks !

The Hammerli (Hatsan) degasser screws on to the valve and depresses the valve. If there were anything "stuck" in the valve the degasser likely allowed the rushing air thru the valve to dislodge it.
Good job fixing it yourself
