Using the needle deep inside the case will get the air bubble out of the case, of course getting the water out to weigh it is tricky, but if you'll weigh the dummy cartridge before and after the fill, you'll get accurate results and won't wreck the case either..

Now, why didn't I think of that?
There is a caveat however. Keep this in mind. All the "excess baggage" weight that you add or subtract from that actual water weight, by virtue of the case and bullet can loose the fine measurement components in the
background noise. That's why we use such light pans with our powders scales. Just wanted to mention that, though I doubt a tenth of a grain one way or the other will be a deal breaker. BTW, if you didn't know this already, add a drop of dish liquid to the water you're going to use to reduce surface tension and the tendency for the water to leave droplets behind, stuck to the inside of the case walls. I realize this falls into the category of common sense, but clean out the crud inside the case before using it, assuming it is a spent round case. That includes sizing lubricant and mica. The hardest part is getting your hands on syringe bodies and points. The drug store is narrow minded. Knowing an EMT or a diabetic is a big plus.
