    Nope but Evri still have a set in the 0-500g range I've ordered for weighing pistons.

    If going for a slightly more stout spring, and especially if introducing some piston weight, you might find that things even out a little with a wider range of pellets?

    Spring wise, I'm wondering if the TX200 Mark 3 spring would suit / be enough spring for this rifle? Failing that, what about one of TbT's HW97/95 springs would fit okay (wondering about the OD here). And also worth looking into the recently introduced Welsh Willy spring to check the specs etc.
    I have a selection of 'lighter pellets including JSB 13.73 gr waiting to a test a project Meteor so I'll bring the Kral to that party.
    Last night I dug out a Titan #13 meant for my paratrooper but was too tight on the spring guide. It fits the kral sleeved piston a miniscule bit looser but Lyndons spring lube will cure that and is a tight fit on the guide but not so tight that you cannot wind it on like an acetal version.
    I'm definitely going to fit the OE spring first and if it does not improve then it will be fun & games with the Titan.


    Yes it is very Gamo esque just some parts better made.

    It won't be me doing that BC. too great a chance of accidental discharge.
    I once viewed a Meteor at a Nottingham auction house, picked it up, put a bit of pressure on the trigger and it was cocked.
    I decocked it and complained to a staff member. Oh they do that sometimes he said meaning other viewers. it wasn't loaded but can you imagine the bang it would have been made if dry fired.
