Does anyone know the H2O capacity of S&B 7x57 brass?

[rookhawk]

I have a lot of S&B brass and I was wondering if anyone knew the water capacity so I can compare to other brass?

I don’t but have a question…
When measuring capacity with water, do you fill to the neck or all the way full?
Also, is there anything you prep the case with to avoid air clinging to the inside of the case?

I think I only have Remington and RWS brass. Sorry.

I have some S&B brass in 7x57 - message me what you need doing and I’ll happily test it

I don’t know squat about loading, but I do know you can get volume by the weight.
Volume = Weight / Density.

The density of distilled water is the easiest to figure out at a certain temperature.

1 gram per cubic centimeter (g/cm³) or 1 gram per milliliter (g/mL),

I can’t find a piece of S&B brass with an intact primer to measure it. However, if it helps in your comparison quest, I did have an intact spent Hornady .275 Rigby case which I measured for you:

Weight of case with spent primer without water: 178.9 gn

Weight of case with spent primer with water: 238.0 gn

238.0 - 178.9 = 59.1 gn

Why are you not measuring the water capacity of your own S&B brass?

Troy, just for giggles QuickLoad wants you to measure the "internal volume" i.e. water capacity of an unresized case that has been fired in your rifle. Anything other than that is just an "approximation." Send me your specific data and I'll gladly work up a simulated load for you.

All the way full - try to get the water level with the case mouth and avoid an excessive meniscus. Because you want to measure a sample of cases, you want consistency in the method.
Filling with a small syringe usually keeps the mess to a minimum and I've never experienced any air bubbles using this method.
