Default Brass drill bit (for lead)

Don't put anything that's glowing red hot into that barrel. Knock out what
you can with a brass rod, then get an ounce of mercury (you probably can
find an industrial supplier in Thomas Register that will sell you a small
quantity; I bought 4 oz. that way a few years ago). Cap one end of the
barrel with a wooden plug; pour in the mercury to fill the barrel; wipe out
the sludgy amalgam in a week or so.

If you don't whack it too hard, tapping on the end of a brass rod will do no
damage. You may get lucky and all of the lead will come out just by tapping.
The mercury is for stubborn cases. I used it to clean out 40 years of lead
accumulation from the muzzle brake on my Hi-Standard Supermatic.


That's *very* handy - thanks!

I'll tell you all how I get on... it looks like there's multiple pellets
in there, though, from the size of the obstructed region (I stuck one of
my many brass rods in from each end and compared).


If you have it available, then you might consider simply warming the barrel
in an oven to 180C or so, then pouring solder down it.
Also lead will soften greatly at this temp, so you may just be able to push
it out.
