[QUOTE="Mikecr, post: 560927, member: 1521"] Topshot, I'm sure NASA would deareate purified water to determine capacity at various pressures atmospheric. But shooters do not need to consider any of this. We are not certifying our loads, but qualifying them. Hell, the argument here is whether to measure at all! And yes, volume does change until fully fireformed and held stable with minimal sizing(NOT FL sizing). This is when H20 capacity should be checked, and not before. So what happens to velocity as volume goes up? It goes down. Volume up = velocity down. How does this seem rocket science? Bart, many BR shooters do not even verify the measure of their powder, yet anyone with sense knows that powder amount affects velocity and tune. If you had the sense to test capacity variance with velocity measurement, instead of anecdotal hogwash, I believe you would learn something here. But for the rational: EVERYTHING about initial containment affects pressure and timing. [/QUOTE]
