The last target and I am shooting the best since the bone graft surgery. Third record shot sounds funny, does not print where pointed and the case looks like a .32 S&W Long coming out of the chamber. Case rupture.
Get home and try the oversize brush. 35 caliber, a shot of Break-Free, and push from the muzzle. Case neck still stuck. Use a .44 caliber brush and, another shot of Break-Free and the case is still stuck. Then clean the chamber with lighter fluid, a shot of Kroil, ten minute wait, a few choice words, the .44 caliber brush and the case is still stuck.
Next is the Cerro-Safe method. Disassemble the rifle (easy with a Stevens 44 1/2), clean the chamber again, push cloth wads from muzzle to chamber for a dam, pour in the Cerro-Safe, wait five minutes, gentle push and the case neck came out with a gentle push.
Next time, I will just go to the Cerro-Safe approach at the beginning.
Having several hundred back up cases, I will go to them for the coming matches. In the meantime, clean all cases with the tumbler, detergent and steel pins. This will clean them as bright as new and they will be easy to examine for incipient cracks. Examine them and throw out any suspicious cases.
The slight shoulder of the .32-20 CPA must still be a stress collector and cause an eventual rupture.
