Having to take about 800 .357 Magunums apart due to a reloading data error (the 48th edition, anything Bluedot is wrong in .357). and have broken two kinetic hammers so far. Using them on wooden blocks in the shop. Does Dillon make a better tool for this? They were loaded on my XL650 and well the crimps are good :). Takes three to four hammer hits to shake the projectile free. I don't care if the hammer is blue, green or red this kills them when you have that many to take down..
