So where are all the HW57's hiding ??

So, guessing that these may be similar internally to a 99? So 26mm bore. Anyone know the stroke and TP diameter and length?

I'm guessing that the pellet will not be a snug fit into the loading "gate", reducing the SCR massively as the pellet has to jump from gate and it will be a looser fit than a pellet which has snugly clicked into the rifling. After this very easy first stage of its journey it then has to engage breech and rifling, without that helpful thumb / finger of humankind assistance? So, guessing that this will magnify the slammy effect, but might it also then see a spike in pressure as the pellet engages breech, promoting extra piston bounce?

Having said all that, although not desperate to own one, I could actually see myself rehoming one one day.

26mm bore
81mm stroke
3mm dia TP and I think 18mm tp length
