Just to follow up here. You say it took something like 56 pumps of your gun to get one ounce, somebody else said 24 IIRC for them.
Are you guys measuring *fluid* ounces? I ask because I just checked my gun (I've always just used the "6 pumps" limit per Hartzell, but decided to verify it), and 6 pumps gave me an amount by volume that looks by my eye to be about 1 *fluid* ounce...two tablespoons. But by *weight* it was 0.1 ounces, which would mean IF I were to mistakenly use avoirdupois ounces (i.e., by weight), it would take 50-60 pumps of my gun...just as it did on yours.
I'm asking out of a safety concern...did you measure by weight, or volume? Because if you're using a measurement by weight, you are WAY overgreasing the hub.
