Dry lube for springers.

For me, it's Abbey MolyGn paste, but sadly you can't get it any more.

Rocol comes a close second.

So I've been testing, with the standard spring and 1 spacer it's around 600fps with hobbies, with another spacer in the velocity goes down . Similar performance with a hw spring fitted aswell.
   
 I've run out of ideas and more importantly , patience.

tea and bacon sandwich's, that's what you need!

That would suggest that maybe the spring is being compressed too much and isn't then releasing all it's energy. There's a technical term for it but can't remember what it is at the mo. Jim Tyler did an exhaustive article about it in Airgun World back a few years ago, and that's why I'm aware of it.

Think of it a bit like a boxer not being able to deliver a full swing/extension to a punch because his opponent is too close, so the punch is then less effective as he can't get all his power behind it.

Or.......if a housebrick fell two inches onto your head, and then another housebrick fell from two feet onto your head.....which would hurt more?

 I think the technical term is  err   ''oversprung''  .

 I've just registered with these  http://www.sportwaffen-schneider.de/ .

 Should be able to order a service kit-piston,spring and guide.

By jove I think you're right!!!

(I did remember after I posted but then forgot to edit my forgetfulness)



If you think the rifle may be oversprung, then why don't you try lobbing a coil off to see what happens?

If power increases and the recoil goes down (which it will), then you will know which direction to head in.

With the standard spring it's undersprung , adding preload eventually causes spring bind which causes velocity drop, on the other hand oversprung is a different kettle of fish, this is when  the piston moves the air quicker than can be vented down the tp causing lower velocity and piston chatter.

Exactamundo.

What you said about when you increased preload the velocity went down was made me think t'woz oversprung.

Still having problems with lgu , so ordered a lgu spring from solware but received lgv spring , tried it out of curiosity but it just makes it slower and feel dreadful.
 
 Run out of interest and patience with it, time for disposal.
