You guys must be some ham fisted bruts. Slow and easy on the pumps. Just
like a good woman. Everything will go smooth...

I have a gram scale (0.1 gram inc's.) and measure just about every batch
that I have dispensed from the quart size pumps, just to verify the mix.
All have been within about 2 tenths of a gram of each other.

I know of a few guys from the Carlisle, PA area (BAR/CSS Club) that have
laid up a few HUNDRED (read 200-300) handlaunch wings over the past 2

These pumps are accurate, simple and hassle free, I think I'll keep
using mine......
