This pack features small canisters of several powders and is available in a ‘varmint’ version. A great boon to the aspiring handloader is the new sample pack offered by Hodgdon. Once you have searched the loading manuals, you can narrow the choice down to several promising powders. While this formula differs from the recommendations of those who have experience with many types of powders, in my experience it works, and it is the type of scientific notation used by factory ballisticians. It is seldom so cut and dry, but this is how powder capacity is measured. Therefore, the powder charge would represent 80 percent loading density. A 40-grain powder charge would represent an 80 percent capacity of the case. Let’s say that the water capacity is 50 grains. I weigh the case when filled with water, after capping the base. Next, I fill the case with water through the primer pocket hole by using some type of needle or a small jet of some type. I use a dummy case-with the bullet I intend to use properly seated-and weigh the case. I do not think measuring capacity by filling an empty case is relevant. There are various methods of figuring cartridge case capacity, but many are flawed. Calculating load density is simple, but you have to know the cartridge case capacity first.
