When testing and posting your shot strings, You should add the temperatures to your posted strings, When shooting Co2   It will really help those in warm area's like Oklahoma   Lucky Dog!!  I'm in mid Michigan   and the low tonight is 63. I only have one Co2 left,  just to short of a warm season here, With lots of ups & downs.   The rest have been converted over to 13ci Ninja regulated bottle's HPA for better consistency here. The old sheridan pumps are still real popular here.

Tested the gun with the stock hammer/spring backed off 6T or .250" on the PA.
18" Crosman 22 cal barrel with .165" port.
Used 14.3 CPHPs and ran it until it dropped off to get a baseline.
Still amazed at how consistent the shot string is.
Only 11 FPS deviation shots 1-18.
A carpenters dream, flat as a board and straight as a nail.....LOL

Tested at 78 degrees, 3 minute shot cycle.

Installed the 17 cal 14.5" CCS LW barrel.
Elongated the barrel port .125" wide x .210" long.

At 20 yards will pass through both sides of a steel food can.
If it'll go through a can it'll go through a squirrel as well.
Trigger adjusted at 1 lb pull.
Very accurate also.
