I'm just getting to know my press with dillon carbide sizing die including the sizing ball. I was setting bullet seating depth and tried to test neck tension by pushing the bullet into my workbench. I was able to push the bullet into the case. I was concerned that this would be too little tension because I didn't expect to be able to move the bullet at all. However I compared the force (by feel) to a factory federal round and was able to move that bullet as well. I have around 0.002" interference fit between bullet and casing. Is this okay to use in my ar15 or should I resize the cases without the neck sizing ball? I feel like I shouldn't have to do that. All brass is once fired lake city.
