I only have a couple of body dies, but they have occasionally been very useful. I had hundreds of 223 rounds loaded for my 223 Ruger Hawkeye when I decided to have it rebarreled. The new barrel had a tighter chamber than the factory barrel, so no rounds would now chamber. With the body die I set the case shoulders back a touch on the loaded rounds and solved my problem. Luckily, the new barrel was happy with the loads put together for the old barrel.
Am I being over cautious in thinking this may be hazardous to your health?
