hi guys . i owned a very early .20cal rapid bought it in 1994 i think . i was set at 27ftlb which shot some pellets at 1100fps , not accurate .
so dropped it down to 25 and used crossman prems , it loved them (die no 1). when they stopped them in the uk that was it for me . testing against a rapid 22fac the 20 shot flatter and i have taken rabbits at 90 yards with it .
i used it on the back of jeeps partnered by a 22lr and the combo worked well in pest control. i still use a 22fac rapid which is probably 20 years old as its number is in the sub 00500. think my 20 was 00376 0r 00476.
have fun with your new gun .
