On the advice of a friend, I bought and fitted a high-powered mainspring, made from square sectioned wire, and replaced the barrel seal.

Though now very powerful and difficult to cock, the recoil is unpleasant and accuracy not consistent. How can I rectify this?


AIR RIFLES

If you feel unable to spend more money on your rifle by taking it to a professional airgun repairer, then I would suggest you remove the ?highpowered? spring and fit a good quality mainspring manufactured specifically for the make and model of the rifle.

The spring you fitted is obviously unsuitable and could cause damage to the air rifle.

It is possible that damage has already been caused to the piston seal which is 15 years old.

You have already replaced the breech sealing washer, so if you replace the piston head and fit the correct replacement mainspring, suitably lubricated, you rifle?s original performance will be restored.
