place a ball on top of the chamber and ram it home
Nothing complicated here. Make sure the ball's a tightish fit
and If using a cast ball with a pronounced sprue make sure it's at
the front or back.
Repeat for the other chambers
Now, if you haven't used a lubricated wad, fill the chamber
mouths with grease
This is generally a good idea as it helps prevent barrel leading and
damps down any loose grains of powder on the front of the cylinder.
In theory it also stops any chance of a flashover where the
explosion from one shot can detonate the charges in the other
chambers. In MLAGB competitions it's mandatory, for all other it's
optional. You can use just about anything for a grease, from
vaseline to beeswax and tallow to Trex. The classic choice in the UK
is water pump grease, (available online from the
MG Owners Club) which is lime based and actually feels and
smells rather nice, and possesses the significant advantage that it
doesn't melt after the first shot. You can buy special grease guns,
or use a lolly stick, or for a light grease, syringes used for
artificial insemination of cattle work quite well.
