Developing Loads for the .25-6.5PRC

[Wind Gypsy]

This is what I’m getting using a .284 neck bushing. A .287 was barely holding the projectile in place. View attachment 397435

Hard to tell just from the picture other than the obvious coloration changes. Are you positive its the back of the neck that is fitting tight and not the shoulders?

Good point. No, I wouldn't say I'm absolutely certain it isn't the shoulders but I am full-length resizing. I might pick up a cartridge gauge to test that.
