I seem to have more fun with the airguns than centerfire nowadays. Cheaper and can shoot just about anywhere out here.
Can never figure out the best pellets, seems to vary day by day--altitude, temps, wear and tear on seals, and so forth. That is why you keep a dope book!
Recently rebuilt with new seals.

Perhaps your attachments are too large. You may need to resize them.

Best springer I’ve had loves jsb/aa 13.4 and 15.9. Have killed close to a hundred squirrels with it. Real squirrel thumper.

You probably haven't posted enough to be allowed to upload pictures or as noted the file size or type isn't right.
If I recall the max file size is around 1 meg.
Regarding pellets. The best way I have found to test pellets is to buy the pellet sampler sold by straightshooters.com. They package 25 each of 18 different pellets for testing purposes. You will learn a lot by trying them all in sequence. Shoot a couple 5 shot groups with each, then repeat with the 5 best and keep refining until you have the one your rifle likes the best. You might find a couple. Then buy a tin of them and shoot 10 to 20 groups to get an average for that pellet in your rifle. In the process you will get much better at the artillery hold and have better results. In general a velocity in around 850f/s will give best results with most air rifles. Much higher you get inconsistency in the trajectory.
Also, straightshooters has a batch of short articles on the their first page (right-hand column) Read them in sequence and you will learn a lot about air rifles.

I bought mine used and was a TO6 which I polished and tuned the trigger right after receiving it. Built my spring compressor and lube tuned the piston and spring to quite it down some and ran a few pellets over my chrony and found it was a full 24ftlb rifle .
Latter I acquired a TO1 177 D54 and was told by enablers I should put the TO6 trigger in my best rifle which meant swopping triggers and pistons between the D48 & D54 which was no big deal but it also changed the stroke since the stem on a TO1 piston is longer .
Found my spring in the used D54 to be severely bent and needing replacing when it made the swop.
I got a ZRT kit from ARH and put it in the D54 and found it was more spring then I liked for the 177 D54 so I got a GRT bare spring from ARH and fitted a guide and top hat. This was the right power range and made the D54 sing.
The ZRT kit went into the D48 .22 along with the TO1 trigger. Talking with Hector I found I could adjust the TO1 to make it a single stage trigger and Oh boy what a difference that made along with the ZRT kit which tamed the D48 and turned it into a 18 ftlb one hole shooter.
The TO1 was adjusted down to a 3lb trigger pull with no slack or slop and very crisp.
I also refinished the stock and put an adjustable butt pad on the D48 which I found a little short for my length of pull and the pistol grip too blocky for my liking. I fixed the pistol grip by creating a palm swell and finger groves doing a little shaping with my dremel tool and stippled the pistol grip.
Attached a few pictures for your viewing.

Ahh. I see you did the same thing I am getting ready to do - remove my rear sights from them. They just snag up for me and don't provide anything since I only use the scope.
