[QUOTE="Hugnot, post: 2524286, member: 115658"] Waste of time - brass cartridge heads are work hardened at the time of manufacture. Exceeding certain pressure limits for any piece of brass will exceed the elastic limit for that particular piece of brass & will result in getting into a plastic state & enlarged primer pockets - we have all been there. Possibly there might be some industrial process to beat on the brass head exterior to decrease brass grain size and make for more work hardening. An electron microscope, beam of electrons vs. light, could be used to anlayze the grain size as a measure of work hardening. This would determine when an optimuim degree of work hardening was obtained. Exceeding the elastic limit of the brass would make for enlarged primer pockets. The cost of the e microcsope would be about 4X the cost of a low end Razor scope. I would prefer to buy real good brass like Lapua and forget about DIY work hardening. [/QUOTE]
