OK, i have some Winchester 32-20 cases. Unfortunately, the base of the case is thicker than the Graf 7.62 Nagant case.
I searched the internet and someone mentioned to mill the base of the Winchester 32-20 case. I didn't file the whole base of the case, because i suspect that after the filing and primer is seated, the primer would stick out, which is not a good thing; instead, i tried to shave off some brass from the upper rim of the case with a dremel. Well, it didn't work.
Then, i resized a 32-20 case with the Lee 7.62 Nagant sizer die and dropped the case into the cylinder of my Nagant revolver. As expected, the loading gate couldn't close because the base of the case is too thick.
Since the cylinder is spring loaded, i pushed the cylinder forward and closed the loading gate. I pulled the trigger a few times and the cylinder rotated fine! i then tried 6 empty cases and the cylinder also rotated fine without any extra force! So far, so good!
i cocked the hammer and the case in the cylinder could rattle a bit (backward and forward), just like the Graf Nagant case!
because of the thicker base of the case, when the rear 'thingy' of the revolver pushed the case forward, the extra thickness of the base of the case actually helped fill up the gap (which is a typical scenario of using a 32-20 case in a Nagant revolver) of the 'forcing' cone (the thing at the end of the barrel and just before the face of the cylinder). i don't know if this would achieve gas sealing, since i have not started reloading live ammo yet, but it's a good sign.
Any comment and input, guys?!
