lol... quite correct - I dont know what I was thinking!!
This morning I made up a wee brass tophat, 12g - maybe a bit light, and a ptfe sleeve.. its deiselling slightly so I only got one good reading from the combro of 8fpe - I need to find another bit of brass and make up a heavier one - about 20g.. , I also shimmed the sear to keep it central.
next, Ill take the rounded nose off of the oring head and gain a couple mm of stroke. Ill also try a delrin guide as theres still a tiny bit of twang.
one thing that I have noticed about both this meteor and my dads lightning, is the loud 'clack' when the sear engages the piston - is this normal?
