I am just starting out reloading and I am still working out all the details and purchasing equipment. However, I have a few questions. Initially I will be reloading .223. I have about 1500 once fired cases that I have been saving for about the last year. These are military spec brass with crimped primers. What is the most efficient way to remove the crimp from a large amount of brass? Without spending $300 on a Dillon power case trimmer. Is there a way to trim a lot of brass quickly and accurately? Thanks!
