Been thinking about how to know if my annealing technique is consistent and produces same state as a commercial 'correctly annealed' case. Since annealing affects the brass strength I thought about placing a known load on the neck to make it egg shaped and measuring the deflection. And by starting low and slowly increasing the load I should be able to find the yield point. By comparing homemade cases to commercial cases I should be able to tell if they are annealed to the same state. Has anybody ever tried this?
