The Wilson Inside Neck Reamer (L.E. Wilson part no. INR-070) is chambered for 7mm (.284 caliber) brass and ships with a single knob-style handle for turning by hand. Reloaders use an inside neck reamer on thick case necks after multiple sizing and firing cycles, since material buildup in the neck can cause high chamber pressures and erratic shooting. Standard reamer sizes like this one target cases that have already been fired and left un-sized, and the same reamer can also be used when forming wildcat cartridges from a parent case. It is manufactured in the U.S.A., and Wilson notes that special sizes can be ground to order for extended lead times if a standard reamer does not fit your needs.
