I am asking because one flaw of my new cartridge is that, being very sloped the magazine tends to reach 7.62x39mm 30 round size and shape at about 20 rounds if I pack them with just a 0.5 offset.
Also, what kind of bad things would happen if I stacked sloped rounds in a strait magazine? Or rather, if the curve of the magazine is smaller than what would be naturally required by the rounds.

Thanks. But I was looking over the calculator and realized that for the pressure I was using there was just too much spare space in the case. So I decided to make it just a bit flatter. I lost something like 2 grain of capacity which still puts me well above the load the calculator suggests. And my case angle went from 3.3 degrees to under 1 degree.
