Depending on the size of the lube groove and size of the bullet, the number of bullets that can be lubed before pressure has to be reapplied will vary from as few as 5, to as many as 20.
I now own 8 Star Sizers, and none of them have been converted to air feed. They work just fine as originally designed.
I do also own a Magma Bullet Master commercial sizer that uses air pressure for the lube and is motor driven. That's a high volume machine and requires the air pressure to keep up with the volume.
Hope this helps.
