You need to be sure you are aiming at a "hole" that is really there. My plastic bobbins look like they have four holes but two of them are fake. They are not a hole at all, just look like one. If you can't see that, poke a pin in it to be sure it is a real hole, not a fake one.

I have 2 Bernina Electronic machines they both use metal bobbins and I have never had any problems. Bought extra bobbins from my Bernina dealer and they are metal. Have 2 Featherweight machines and they have metal bobbins and no problems.

I ALWAYS have a problem with the word NEVER! But, the logic behind it is that metal on metal friction is greater than plastic on metal and today's machines are so much faster that the friction is much greater than before. With threading, stick the tiny needle threader thru the hole and slide the thread in and pull. Should work for you.

Learn from my mistake: NEVER use metal bobbins in a plastic drop-in bobbin case. Several years ago I had an old Kenmore front load machine and replaced it with a new Kenmore machine with a drop-in bobbin case. Because I had a lot of filled metal bobbins, I began to use them in the drop-in bobbin machine instead of using the plastic bobbins which came with the new machine. After several years of making quilts, the metal bobbins created grooves in the plastic bobbin case which eventually caused the machine to fail. The new bobbin case cost several hundred dollars to replace. I learned my lesson.
