What do you all feel is some of the most desired wildcat cartridges. I am planning on rebarreling a couple rifles and my thinking was that i could chamber for some type of wildcat that requires brass to be fireformed. My thinking is i can shoot the load and sell the fireformed brass, ie. chamber for a 22-250AI and shoot standard 22-250 loads for my shooting and then sell the ackley formed brass. The last ackley i owned, the fireforming loads shot just as good if not better than my Ackley loads.
