[QUOTE="SidecarFlip, post: 793943, member: 39764"] Get the old Vicegrips out and do the springback test. Take a known good cartridge and apply the vicegrips to the point where the neck deforms upon closing and release the vicegrips. Note the amount of return to concentricity and then, without adjusting the vicegrips, squeeze a suspect cartridge and note again, the return to concentricity. If the cartridge is too soft (over annealed) it will stay squished. if it's brittle (inadequately annealed), it will 'spring back to concentricity more so than the known cartridge and/or crack. Thats the cheapest and easiest way to ascertain elsaticity in the neck. [/QUOTE]
