Working with the orphans.
Can’t be the only one with PCPs that I like well enough to keep, but never really worked out as well as I had hoped. Like the rifle just don’t much care for its dynamic handling. So they stay home more than goes out in the woods.
ORPAHN #1:
“Petunia” (the short/fat/pot bellied pig).
Never did work out as well for hunting as I had hoped. At 9.3 pounds and 35.5 in length. It’s a chunky-monkey. Odd stock actually fells good, but looks pot bellied (which is why she is "Petunia", as in "Porky’s girlfriend).

One of the few PCP's that actually looks better with an LDC:

Not the most efficient rifle in the safe, but moving normal weight 5mm's at a reasonable speed (can add 20fps for 13.7gr. JSB's):

Either one of the “odd” ones or one of the “typical” ones. Without changing ANTYHING besides the spring tension:
1. The shot count goes up.
2.The working pressure goes up.
Am thinking this is how a PCP SHOULD BE. Will try a full 3K pressure and see if I can get it up to 24 foot pounds for the same number of shots.
ORPHAN # 2: ‘Fugly” (looks like a plumbers nightmare)
Was never happy with it as a PCP. Wasn’t excessively happy with it as a co2 (esp. as my favorite paintball shop closed). Tri3ed it as a 5mm HPA and wasn’t too thrilled.
Reworked it today as a .177 HPA.
Some time back and converted a 177 barrel from a junked Gamo 126 ( SSP match gun). Made black delrin barrel bushings that were a hard-push fit inside the frame.
Took out the4 5mm bsrrel and dug that .177 barrel out of storage (it ended up at 14” rathan than the typical 12” of a TalonSS).
Set if for just about 12 foot pounds (11.7 foot pounds) and tried 4 different pellets.

Nice thing about HPA is that it is proportional. If it takes 700Psi to make 60 shots, then 1800psi (3K to 1.2K) should make 2.57X that number of shots fropm a full 3K fill, which workes out to be about 155 shots.
