Not really, as the small bore has less air to compress, and that air presses back over s smaller surface area, reducing the decelerative force, so the piston is decelerated less, so it's overall journey time is actually shorter... however, see below...
Been running some numbers on the top secret funky recoil simulator:
Bore & Stroke / exit time / piston bounce dist / action dist / max piston bounce
25mm & 78mm / 10 / 5.9 / 4 / 28.4
22mm & 92mm / 9.7 / 7.7 / 3.8 / 36.9
lock time (pellet exit time) is actually a fraction quicker on the 22, but the difference is tiny.
the action dist recoil is 0.2mm less, but also a tiny difference.
The far more significant numbers, I'd suggest, are the piston bounce distance (at pellet exit) - the 22s piston has bounced back 7.7mm, the 25s only 5.9 Still not a huge difference, but definitely the most significant so far. Max piston bounce (ie after the pellet has left) is also a fair bit great too...
Maybe this is why ?
Maybe we should make our 22mm pistons heavier....
