Not really. I've got one package of #3 and two of #4 left but not enough rocks ready for either stage. The tumbler instructions say not to go under 8 oz. when running it, and I've got 5-6 oz. ready for #4 and 2-3 oz. ready for #3.
The tumbler came with two packages of each level, but I've found that no matter how much time I have the tumbler run, it's too short a time for some rocks and is often too long for others. I need to experiment a lot and learn to tell the relative hardness of rocks we've picked up off the ground so that I can group them that way and expect them all to reach the same level at the same time. It doesn't help that I've not figured out any way to check the status of all of the rocks in the tumbler without dumping everything out and needing new grit even if I want to keep on at the same level.
