The Forster Wildcat Neck Reamer for .243-inch bullets (Forster part no. NR1239) cuts a .2390-inch inside neck diameter in cartridge brass. Forster lists it as a standard, off-the-shelf wildcat size, so it is used after sizing rather than before, which is the opposite of how a standard neck reamer is run. It mounts in the cutter of a Forster case trimmer in place of the pilot and removes excess brass from the neck walls. Thick case necks can cause high chamber pressures and flyers, which is the problem this tool is made to clean up for handloaders working with converted brass.
