Description Thanks to the unique way the case is locked in place in the shell holder, this trimmer accurately restores fired cases to the correct length no matter the thickness of the cartridge rim. The lever locks the case in place. The Micro Adjust cutter allows .001" changes without moving the case (extra cost on competitor trimmers). Plus, its large diameter, replaceable cutting head is made of ultra-hard tool steel and trims cases up to 50 caliber. Use only Hornady brand shell holders and pilots with the Cam-Lock Trimmer. Other shell holder brands are not compatible with this unit. The Hornady Cam-Lock Trimmer uses standard Hornady removable shell holder heads so you can use the same shell holder head in your trimmer and your Hornady reloading press. The Cam-Lock Trimmer can be mounted on a bench or clamped in a vise, and is adjustable for all sizes of cartridge cases. Firearms, trailers, and some accessories are only available for purchase in stores. Each location follows all BATF and individual state/county/city laws to insure the desired product is legal for sale.
