I have a few Hawks & Vulcans I never would have guessed that you could get the power up to the legal limit on them!

Ive owned. A mk2 for 40 years in the early years I had a floating tube of copper to act as a make do guide, not bad as I was only 14 when I did it. More recently had the factory pathetic factory guide machined down and fitted a delrin guide, sleeved the transfer port ( thanks mick), squeezed up the breech jaws, swopped to o ring piston seal. Shoots lovely now though still 8fpe. Would like to mod the piston but lost my lathe friend so it's staying as is for now.
I fitted a floating guide, along with a Meteor mainspring, in a Mk.3 Hawk many ears ago, which worked well, no machining necessary.
I later made a guide and 'dummy' piston rod for a Tracker.

Been thinking about using a Meteor spring in the Hawk as well. Jim Maccaris Meteor spring is superb in my old meteors, and as the Hawk is a 25mm/1" piston like the meteor, it seems like a sensible choice.
How do you ensure that the floating guides do not end up all the way forward in the piston? Do they reset position with every cocking stroke?
I had an extra Hawk piston in the box of webley parts, and comparing the two pistons I found that the original piston in the gun was not rounded the same way at the edge where the spring enters at the rear of the piston. The spare piston seem to be unaltered, but was radiused at the rear. Changing pistons made a huge improvement in the cocking stroke!
