For years I have watched serious reloader carefully trim their rifle and handgun cases to a precise length....then geap up a chamfer tool and grind away. This is "A" alright with rifle cartridges with no roll crimp! However, upon examination with a powerful glass, you will find no two just alike. With this in mind, how can any rolled crimp be uniform, crimp to crimp? They will look good outside, but what about underneath? If loading is done properly there is no reason to chamfer a pistol round. A better procedure, that will give perfect crimps and bullet pull, is as follows. First, go ahead and trim, even a few thousandths under what is classed as trim length. This allows for some buildup of lube in the front of the case. Then twist the cases in fine steel wool. This will take out any burrs. Now if you look at the mouth of the case you will see it is somewhat square. Great! Now slightly bell you cases with your expander die. Seat the bullet without crimping, down to the crimp groove in the bullet. Follow up with a good rounded crimp. Now each and every one of those loaded rounds have the same exact bullet pull! Think about it! Best Regards, James

Take a 5/16" x 2" long bolt (preferably one that the threads don't go all the way to the head) with 2 nuts and 1 lock washer. Take a 3/4" copper pipe cap and drill a hole in the center of the cap big enough to fit the bolt.

Put one nut on the bolt followed by the lock washer. Now install the cap followed by the remaining nut. Bolt threads should be flush with the top of last nut. Tighten well.

Now cut the head off the bolt and file off any burrs. Pack the cup with steel wool well and to the top of the "cup" of the cap.

Chuck the gizzy in an electric drill or drill press and hold the mouth of your cases flush against the steel wool in the cup. Oopy Doopy! Takes the burrs right off the case necks in short order! Nice and square too.

Have Fun!
