Are there any alternate springs available that will yield 10 Ft-lbs+, given the lighter piston, such as .113", .118" wire or greater, outside of the factory spring, which is what .125"?, and still fit nicely inside. Looking at ARHQ or Vortex springs for example. The trigger looks great on your rifle, what is its weight adjustment range compared to the factory trigger? Vs

Krytox and Ultimox will detonate in 22mm set up, the reason is the pressure generated is super high, keep that in mind and go sparingly with what ever you use. I prefer STP as it gives the lowest friction set up and it lasts a decent amount of time, and you only need a drop 22mm can generate 1600+psi, 21mm 1700+ 20mm 1800+
Several years ago, I put a full power vortek kit into my D34 using ultimox. The internals were thoroughly cleaned with brake parts cleaner and lacquer thinner. Tube was deburred, lightly honed and lightly lubed with ultimox only. It was shooting very hot at over 16 FPE in .177. During the initial 25 + shots, I would get a puff of white smoke from the breach upon breaking open the barrel to reload. Did I somehow leave trace amounts of oem lube somewhere? I don’t think so. I run my 3 stone hone while the tube is submerged in a bucket of warm soapy water. That plus several cleanings with solvent should have sufficiently removed all prior lubes, and yet I got a very odd smelling smoke.

Matter of fact, I didn't believe the "no dieseling claims" at the beginning so I deliberately lubed my HW95 internals liberally, including some on the face of the piston seal.If you're getting detonation with a sub 12fpe setup (even with a 22mm "compression tube") using Krytox I'm thinking that you have some "petro lube" (STP?) getting mixed with the Krytox somehow. Matter of fact, Dupont Krytox is used for lubing parts used with oxygen because it won't burn..........From the above............"Krytox™ GPL 100–107 oils are clear, colorless, fluorinated synthetic oils that are non-reactive, nonflammable, safe in chemical and oxygen service, and are long-lasting."And"Krytox™ GPL 200–207 greases are white buttery greases with all of the same properties as the Krytox™ GPL 100–107 oils that they are made from, but they are in gease form."Anywhoo.....I've used Krytox with my .177 HW95 (admittedly a 26mm receiver) and oring sealed piston cap tuned as high as 14.5fpe and so far not even a diesel much less detonation!
Gents, this is one of the reasons i was VERY reluctant to ship to the US, Steve gets the sub12 thing, many do not, if you are looking for over 12fpe, stick with something else...im being VERY honest here.Tony

VsThe kit is not designed to deliver +12fpe, its designed for 11.5fpe or so, this is NOT an FAC set up especially in .177. It was designed from the ground up to use the factory TX355 UK spec 16J spring, yes i have run other springs BUT they run seriously low preload settings and again the kit when pushed over 12 especially in .177 something (probably the rear guide) will fail.Another reason for the TX355 spring comparing to the soft vortex springs is the ID of the spring, its near 15mm, which yields a thicker wall on the guide for more strength.Gents, this is one of the reasons i was VERY reluctant to ship to the US, Steve gets the sub12 thing, many do not, if you are looking for over 12fpe, stick with something else...im being VERY honest here. The reason for using TX355 is you can buy them from many places, they fit the guide and they work Tony
