Hawk MK1 mainspring and fun

[T 20]

My MK2 is an early one with the MK1 style stock, I always took it that Webley just used up MK1 stocks on the early MK2s --- but the stocks are completely different as is the cylinder and stroke (I'll try to stick a piccy up later).

As promissed --- Hawk MK1 and MK2 actions side by side

As a bit of an experiment Mick, could you try a Ptfe seal with a smaller hole in it and let me know the difference in fps or ftlbs, compared to a standard seal? I know you say that it wont last I would just be interested as to what it does, because I found that it moved POI on the 2 guns I tried it on and it SEEMED to be hitting the backstop harder (No chrono obviously)

Unfortunately Guy when I got my Hawk MK2 out I noticed that some fool had sleeved the transfer port down --- I can't even remember doing it.

So I can't try your experiment.



Here's a picture of my spare cylinder showing what the sleeve looks like when fitted.

Now I'm pretty sure that I haven't put a new spring inside the complete .22" Hawk MK2 shown since about 1977 so I ran it over the crono to see what power it was putting out with the sleeved breach --- 9.46ftlbs with 14.5 grain pellets.

As I couldn't remember fitting the transfer port sleeve perhaps I have been inside it, I'll just have to open it up over the weekend to check, but I'm 100% sure I've not bought a spring for it since 1977.





All the best Mick
