and an Air Arms S410 carbine pre-charge
pneumatic in 22 caliber.
You know that you can alter the muzzle energy of the S410 don't you?
When I bought mine ( a few years ago) it was set at 9.8 ft/lbs muzzle energy,
which was annoying because it could have been 12 ft/lbs.
If you place the rifle on a table, stock to the left, trigger side towards you,
you will see a number on the barrel.
About two inches towards the muzzle - i,e, to the right of the number,
you will see a small hexagon headed screw.
Undo it, and put it somewhere safe.
Inside the hole you've just revealed, there is a small screw at the bottom.
Move it anti-clockwise (unscrew) and the power increases, clockwise (screw in) and the power decreases.
Use a chronoscope to set to the required muzzle energy - I used a Combro cb-625 to set mine.
Replace small screw you originally removed.
Re-sight if necessary due to altered power and therefore altered flight path of pellet.
If you increase the power, you obviously decrease the number of shots e.g. from say 80 to maybe 65 before recharging, but that is a lot of shots anyway.
