Big Grin reading all the comments. Gosh!!!
I have three HW95 rifles, two are older ones and one is about six months old. All of them have some percentage of barrel droop. There is nothing wrong with the rifles, it is what it is and they will all shoot one hole at 40 yards with their respective favorite pellet.
Get rid of the UTG products, this may or may not be half of the problem. Also you should try to keep the scope as low as possible if you want to shoot longer distances as this helps flatten out the pellet ballistic curve.
AOA will simply tell you this is a common issue.
Solution purchase yourself a set of adjustable Sportsmatch Rings, yep they cost around 80 bucks now, however they allow you to optically center the scope and then using the rear adjustment sight the rifle in for elevation using only the rings. Now you are all set. Worry not about all the Urban Legend Tales that the adjustment screws will vibrate loose and create a constant tighten and adjustment issue.......that is simply Urban legend repeated over and over and has no basis in fact. All break barrels have some degree of barrel droop be they a Gamo or high end German rifle. Sportsmatch adjustable rings mounted on the dovetail as low as possible with the rear retaining ring stop pin securely in place will fix all your problems. I have a Gamo .22 Swarm Magnum that actually had the opposite of barrel droop, it shot two feet high at 25 yards, so I used a set of sportsmatch rings for it and used the front adjustment for that one. I just finished the sixth tin of 500 pellets in it several days ago and those rings have held secure, as has the Vortex scope.
Adjustable rings, mount low to the bore as you can, and barrel droop is to be expected and is simply a part of owning any break barrel.
The HW95 is a fantastic air rifle, it is frustrating to a new shooter to experience this kind of situation.....I get that. Grin! However you can expect one inch groups at 25 yards with no experience at all, as you learn the rifle and develop your skill with it, one hole is repeatable at 40 yards. Hint.....both the GTO 11.75 Predator and the FX 16 grain (same as JSB 15.89 cept it taint the fx seem to shoot better) work in all my rifles well.
Take a deep breath and start over......The 95 is a fantastic rifle.
