A HW 97K and they were terrible, even sorted and weighed. Yet, they are the go to pellet for my modified Crosman 1720T competition pistol. It is just shy of 12fpe at 11.58 fpe.
They fly perfect from that LW barrel. The barrel is around 14" and that short barrel and manufacture might be the difference.
Now that said, I noted a large amount of the tin having distorted skirts! I mean bad!
It should be noted that the Air Arms 8.4 pellets are just as good in this gun, and all other 12 fpe rifles I own....Just saying....?
