222 Remington “case study”

This is a very important part of reloading - to keep your case volume under control. There is a reason why the reloading manuals state which brand of brass they use - simply because their data is only applicable when you use the same brand. In this case as shown in the video, things become a bit more difficult. This is because there are different weight classes of Norma 222 Remington brass and I managed to get hold of a few hundred cases which fall into a total of three categories. This is not exactly ideal as a maximum charge in a lighter case (i.e. bigger case volume) will result in an overload if the same charge weight is poured into a heavier case (with less case volume). If you really want to understand the problem you can picture the light cases as 223 Remington cases and the heavier ones as 222 Remington. Needless to say but if you load a maximum charge for a 223 Remington into a 222 Remington case, you will have a potentially dangerous issue with overpressure.
