What's wrong with my gun? — Look at this shot string!
● Gun: RTI Prophet 2 Compact Performance .25cal
● Pellet: .25cal — JSB Dome 25.39
● Balanced valve

● HST: About 1/4 turn further in than the setting where velocity drops off rapidly.

▪ AIR pressure in 240cc bottle 290bar
▪ REGulator 145bar





And the MV shows a decline by about 20fps.
This decline continues.
➧ Very ungood.
