I bought a new motor, collect it on Saturday.

Anyone want to hazard a guess, I’ll give you a clue it’s got 288bhp more than a Renault Twizy (which has 6.1Kwh - you’ll need to convert that to bhp).

Yes Franky....as long as muzzle velocities were the same then the drop at 60 yards from a 40 yard zero was near identical.

i.e........800fps .177 zeroed at 40 yards compared to an 800fps .22 zeroed at 40 yards.........both had the same drop out at 60 yards.

Hope I've explained that OK!!
Thank's Gambo All is true.....Franky

I've not seen the vid, but I'll have a search for it.

It sounds sorta similar to a Hatsan AT44 I had. That would start on bang on power, but gradually drop velocity as the cylinder pressure went down. I suspected the transfer port was too small, but as the rifle was new and under warranty, I didn't open it up.
It was no biggie, as long as the cylinder pressure was not allowed to fall too low, accuracy was fine........but I knew the rifle had the potential to perform more efficiently.

Way back when.......I had the same thing with an S310 that I'd fitted with a Terry Robb 3" hammer spring to supposedly improve 'lock-time'. The slightly stronger spring gave more (too much) power, so I had to choke it down with the transfer port grub screw to keep it sub 12. Doing that then made the rifle drop off the charge too quickly.....as the cylinder pressure dropped the air didn't then have enough ooomph to force it's way past the almost closed port. At about 140bar it feel off a cliff. Refitting the standard hammer spring and opening the port restored the balance, and SPC efficiency returned to as expected. The faster 'lock-time' I'd been searching for didn't make a blind bit of difference to accuracy......it was all cons, with no pro's.

That episode taught me a valuable lesson with regards to spring rates.
