Gun now performing very well but compression tube is getting scratched at the bit which shows.
There is still a fair bit of meat left on the 3 plastic studs and bearing. No sound of grinding.
I have polished scratches off a couple of times but they come back.
Any suggestions?

The best I have tried in my prosport are accupels. However, they are all different. Pellet Perfect sell sample packs of 25 pellets for about £1.50 a time. Easy to try a selection for the price of a tin. Remember to shoot several of each new type before testing , in order to get the new lead into the...

I used a piston extension. I expected a bit of a drop but not to pistol level. I can't say the gun is particularly hold sensitive. I shall probably leave it as it is now, then again..............

I have attached a leather strap to the butt screws and have a leather loop on the barrel.

Be sure to put several through the barrel before testing them properly as old and new pellet residue sometimes d...

I have a HW 90 in .22 calibre for sale or swap for something in .177. Gun is in excellent condition. Shoots very well and is silky smooth. Comes with a Hawke sports scope.
Looking for £300 or swap for TX 200 etc in .177.

As I am now in spring only mode and have to carry a pro sport around a wood I want to attach a sling. I am not keen on drilling holes in walnut so the questions are : Can a sling be attached to the butt pad screws via a leather strap without tearing screws out and can a sling be attached to the barr...
