what powder charge in those
pull a bullet weigh it find out what the charge is
Nothing wrong with pulling a bullet and looking to see what is inside, but the charge weight won't help in duplicating the load. Ammunition companies buy "unblended" powder, something that is not available to us unless we buy pulled surplus powders. The powders we buy over the shelf have been blended with faster and slower lots to produce a consistent pressure curve, by weight. Which is why reloading data is by weight, not volume, because they don't control the pressure curve by density, it is controlled by weight.
Once you research this, it is surprising how many products, particularly food and drink products, are blended to a standard. There are taster's whose job is to ensure the "brand" taste is maintained. Mother nature varies in so many ways, and gunpowder varies each and every lot because the ingredients and processes are all a little different each and every lot. So, for the powders we buy, they are blended.
An ammunition maker has their own pressure and chronograph gages. I have been told the instrumentation on primer testing is beyond my comprehension, they measure flame temperature, duration, mass ejected, etc. So the ammunition maker will buy cheaper un blended lots that are within his specifications, then find the correct charge weight with his gages.
Pulling the bullet on commercial ammunition and weighing the charge won't produce duplicable information as you don't know the burn characteristics of the propellant inside the case.
