I made this post BC I had bought a custom build warbird and I had no knowledge of the rifle prior to purchase. It came with 100 rounds of once fired brass that I have sized and primed and no loose pockets. Since then I have changed the load to shoot the 210 vlds with retumbo. In my load work up I have shot and reloaded the same 12 cases 4 more times and have not had a single issue with them accuracy is amazing with a 1:12 29" barrel. Looks like dpo and I got the only good brass for this caliber. I am looking into an annealing setup to hopefully extend the life if anyone has input on which one I should look into
