Noticed a fellow posted at Airgun Nation Forum (June 29/2021 4:52 AM) that his RWS 48 .22 will shoot one ragged hole at 40 yards and shoots JSB 18.13 grain at 870 fps MV.
No one responded and said are you sure about that? are you crazy? etc. That's about 30 and a half foot pounds energy.
Possibly a highly tuned/modded D460 or D350 .22 or .25 exists that produces mid 20s or so but no where near 30 FPE!!
Most of Diana's magnum springers in .22/.25 will be somewhere between 21-24 FPE tuned, spit shined, whatever.
I've seen soooooooooo many posts like the aforementioned that no one says a damn thing. Some guys would get madder than hell
at me back when I was on various AG forums because I would say something.
