What everyone said was helpful. But I personally would hate to shim my scopes. So I opted for a better scope which fixed my problem with droop right away. That plus copper pivot washers and more pellets through it. With the new scope, moly, deburr, new seals, copper pivot washers it really helps the droop, I have lots a room for adjustments on the scope, so no problem. Your Trail will come together. Could take the 'easier' route and shim, or just buy a better scope if possible, which will come with better rings too . BTW I have a Leapers 4-16x40mm True Hunter on my Trail NP .22 AW. Cool scope, cool gun!
I first attempted to sight in at 50yards
...I have about 100 rounds through...
I think you'll see better results at any range after atleast 500 pellets. For mine at least, the Crosman caution of atleast 100 pellets is a little too low for break in, NP or not. And sorry, I've never seen a 30mm to 1 inch adapter before. Try the brass washers from Gene, put a cheap 500 tin through it to break it in, I also put in new breach seal, piston seal, moly'd, sanded compression tube and piston, cocking lever arm and receiver.
