38/357 Bullets, lead cast semi-wadcutters. Left over from a project, I have 105 of these, cast from wheel weights, sized to .358 and lubed with liquid Alox. They weigh in around 165 grains, +/- 2. I don't think there's really that much variance, I suspect it's because of the bullet lube. 105 gives you a few to work up a load and then a full 100 to load. I think there are a few hundred more of these somewhere.
