So, I have a Lee "o" Frame press and I reloaded my first 20 30.06 by myself. When I went to the range, I was shooting just fine and then I couldnt chamber one of the reloads. I removed it from the rifle and found that the shoulder appeared to be pointed, like it was compressed in the press. I looked at the rest of my loads and found a few more just like it. What did I do wrong?
