    I'll make a note of that, thanks Nick. I bought mine 2nd hand, but I heard that there's now a UK distributor for the Vortek stuff.

    You could try putting a chamfer into the transfer port outlet to create a volume for the air to expand (lowering temperature a tad) before it reaches the o ring.

    Nick Try using a HW97 Breech Seal with a small spacing washer behind, shouldn't rip through that quite so fast.

    I have tried using the 97 seal + shim but I had problems then with the transfer port damaging the lead into the barrel.Rightly or wrongly I put it down to the waist of the HW seal compressing too much. I am now using some breech seals that I got from Wonky Donky some time ago & they are lasting longer than the standard one

    Did you re-establish the chamfer on the transfer port

    ahh that is strange as the HW Breech seal is much harder than the o-ring seals originally used, not seen this issue in any of the set ups i run with it, maybe a different batch of seals?

    I have a titan No 12 in my 21mm now , very close to the vortek dimensionally and makes the power easily with around 10mm of pre load , when at full stroke , Nick 2 's gun is running a shorter stroke so more pre load .

    Sounds like the lock up is too tight. I have a standard TX that shredded the o-ring, but I caused this by setting the lock up very tightly. I took material off the forward edge of the shoe, a Maccari tool steel one, until it just touches the breech as the cocking arm pops into the detent. Seals are holding up much better and velocity hasn't been affected.

    If this is the 21mm , and barrel i did for you, the underlever latches as the port contacts the barrel, people disagree with me , but to my mind , once the comp tube is all the way up, it creates the o ring groove so the breech seals work properly , also there is no slack to be taken up on firing , and the pellets are seated flush all in one go .

    I've fallen in love with Tony Leach. I got my piston conversion from Tony yesterday and took a coil off the spring. dressed the ends, a little krytox on the new dual seal Tony spoke of, a tiny bit of molly to preserve the standard tx spring. WOW what a beautiful thing it is to shoot. the recoil seems non existent as its such a gentle little nudge. with unweighed 849 grains pellets its running a bit hotter than I would like but ive fettled with the ends of the spring, collapsed a coil a tad and I'm getting such a good reading I dont want to change anything yet. I put a 15 shot string through and got one high reading at 797 and one low at 783. the rest were within 789-793. Im going to put a tin through and settle it afterwards at a much safer range of around the magic numbers.

    very very happy with it.

    I scored a 45 ex 50 at GP5 Bisley yesterday with my Tony Leach 22mm internals - and it's only doing 10.2 fpe.

    Gents I do a 1 piece TX200 etc breech seal now, 85s rubber, you can lap it down for an exact fit as its a midges longer than 2 brand new BS108 o rings stacked...why piss around with 77 seals with a washer/spacer when you can have something specifically made to do the job and with it being longer allows you to adjust lockup and seal so its perfect.

    I do them for the LGU also...TX left, LGU right
