I'm trying to start reloading some 380's on the new press, but having problems finding load data. I have both Russian "Unique" and Alliant Bullseye. Most of my manuals are old - but I put a lot of trust in "Reloaders Reference" which was downloaded from here (or Cast Boolits).
Here's the problem: with either "real" Unique or Bullseye, the heavier the bullet, the more powder they allow. Say what? If I'm allowed 3.3 grains of Bullseye with a 100 grain bullet, why only 3.0 grains with a 90 grain bullet? I wouldn't think it's case capacity - Bullseye sure doesn't bulk much.
