Prob w/ HDD was likely MY FAULT.September 17 2011 at 5:50 PM

Seems like i had a simple lubrication problem that was causing each successive cocking to get worse;
I polish out the hammer tubes on my guns w/ mothers billet and then i dont lube them,
[per instructions from Daystate on polishing their slingshot, they advise leaving it dry so lube wont attract lead dust to valve stem etc.].
Yesterday, after approximately 200 faultless shots w/ HDD, the cocking pull started getting really hard.
I tried lubing w/ graphite and it got worse. [i Dont like to put oil near valve Orings].
I stripped and cleaned whole hammer assembly, and tried it dry, no help.
Tried to lube w/ remington dri lube, [coats w/ teflon] for marginal initial improvement, followed by return to poor form.
Tried again today w/ 3 in 1 oil on striker and bolt channel and it seems to be working smoothly again [fingers crossed].
I think the initial break-in phase w/ HDD caused some wear in the hammer tube, [i could see it in the tube]
maybe some shavings/ detritus accumulation in the striker tube messed up the glide, then my graphite gummed it up some more,
and the teflon coating was not up to the job. The 3 in one seems to be working. next time i strip i'll buy and put some moly.
I did not try change the set screw on the HDD, as length/tolerance seemed least likely problem given nobody else has had an issue with it.
