Well I have some dies to make 224 bullets out of 22 rimfire brass and really slow part is placing cores in the brass. I have see one fellow post a pic of a series of plastic drilled to hold the brass and shakes the cores into them. Not sure if hes hand placing the brass in then shaking the cores in. We all the people that are coming up with great ideals I am sure someone has come up with a good way of getting the cores in the brass. Out of all the steps of making bullets this for me is the worst part of the process. So lets share some ideals or pics.
