I Think I Loaded the Grease Gun Correctly ...

 Bought a $12 grease gun today.

Read Steve's instructions.  Too lazy to find them again.

There were instructions with the gun.  Tossed those, cause the print and
diagrams were tiny.

Here are the conclusions I came up with by looking at it.  Tell me how I did
...

a)I think that the rubber plunger goes in the end of the grease cartridge
with the plastic cap.  (Reason, the plunger wouldn't make it past the metal
lip of the other end, I think.)

b)I think that the end of the grease cartridge with the metal cap and pull
ring goes towards the grease gun pump mechanism.

Seems to be pumping fine.

One thing I'm not getting is why invest in the metal cap and pull ring?
Would seem easier just to put two plastic caps on the ends and have a
symmetrical cartridge ... but what do I know ...

Just let me know if I might have got the ends mixed up.

Grease is coming out of the right place and not
out of any wrong places. What part of this do
you find worrisome ?

 
I considered the remote possibility that the rubber plunger thing was
supposed to go through the end with the metal lid and pull-ring and that the
end with the plastic cap was supposed to be closest to the pump mechanism.

I'm not too worried.  It is a $12 grease gun and a $12 tube of grease.  I
can play that game a very large number of times.

I think you paid far too much for the grease.

The reason there are two different ends has to do with how the grease is put in
the tube at the factory.  There can be no air bubbles in the grease tube.  If
air gets in the pump, it stops pumping.  When you popped the metal cap off, you
saw that the grease was right there, no air pocket.  On the plastic cap end
there was an air space between the grease and the end of the tube.  That's where
the rubber plunger goes.

The grease is hot when it's put in the tube and it cools.  And shrinks.  There
is no practical way to insure there are no air pockets on both ends of the tube,
so they make sure one end has no air pocket and fix it so you *have* to put that
end next to the pump.

They could put two plastic caps and then there would be a 50% chance that you'd
put the air pocket near the pump and then it wouldn't pump.  With your track
record, it's probably greater than 50%.
