I just bought a Plews mini grease gun that takes 3 ounce cartridges. Can
it be loaded with bulk grease instead of using those expensive little

The instructions don't say anything about it, and I don't see a good way
to bleed the air out. Thanks.

I vaguely remember my dad filling his by hand. It involved a piece
of shingle, a lot of patience, and shaking the gun to get the grease
settled. It was tough to eliminate the air pockets that would keep the
grease gun from working. He bought one of these:

and life got easier. I have no idea if the $60 investment ever paid
off. He used it to fill his regular sized grease guns for farm equipment.
The other thing I remember is having to leave the business end of the
gun slightly loose at first to let the air out.
