    Great thread and lots to digest here so thanks for sharing. Always fancied having a bash at tweaking an old gun.

    I've used it on several pieces of machinery and the results have been very disappointing indeed. It works well as a penetrating oil, but is pretty useless as a lubricant and hopeless for rust protection.

    I use a lot of GT85 - on the various motor/pushbikes/garden tools. Prefer it to WD40, in fact. Fine for gears/chains, show no signs of rust/seizing, kept outside all year round. The garden tools get a heavy coat over winter. But have only ever used it to soak a seized piston on my guns. Think it's too thin/not durable for gun use.

    Here's a great test of various lubes and their rust protection results.

    What’s everyone using these days instead of the dri slide? I’ve seen “Phillips Molybdenum gun lubricant” for sale , has anybody had any luck with that or any other suggestions ?
    Or should I just apply the moly grease as thi as possible to the inside of the chamber?

    Depends on the gun. The 25mm piston 77’s seemed to benefit from opening to 3.9mm, modern LGU/LGV were similar. How much air are you shifting and what is the current volume of the TP?

    A simple spring gun they say

    My Cometa 300 compact.22 has a TP of 4.00mm x 12mm
    The .177 fusion has a TP 3.25 x 12
    The 220 compact.22 TP 3.00 x12

    All share bore size but strokes a little shorter on the 300-220

    I want to fit a full length .25 barrel to the 220 and hopefully find a TP that allows a barrel change without any internal changes

    I now see Cometa change their TP’s to suit what cal/barrel is being fitted

    My 300 and 220 share the same bore, stroke and calibre.
    The pistons are different and the 300 makes 10.8 and the 220 10.2, the 220 feels nicer to shoot and has become my go to gun, but at the range at 30yds both make the same 20p holes with 10 shots, the 300 definitely has a snap to it and feels lively compared, and I never thought it would be as accurate.

    Ive now added a 7mm SS nose with a hwBritseal and dropped the power to 10 and it feels nicer in the shoulder. I can feel how much quicker the 300 is but another range visit to see if accuracy has changed is needed

    Spring Gun Tuning lubrications

    I have been recommended red lithium grease to use instead of Molly.

    Has anyone a view on this.


    Many thanks

    I have never looked into red lithium grease for lubrication duties on springers so couldn't say for sure. However, moly is proven, plentiful and not expensive anyway (especially for the very small quantities needed), so I would say stick with what we know works.

    Its all about what to use where.
    Moly paste is great for lubrication of metal-to-metal surfaces, like the rear skirt of pistons without synthetic bearings.
    On synthetic spring guides, other lubes can be good, I prefer PTFE containing greases on tight guides.
    Thicker tacky greases like I suspect your red lithium grease may be, can be used sparingly to reduce vibrations when guide-to-spring fit is sloppy.
    Too many airguns!
