The Little Crow Gunworks Big Boy World's Finest Trimmer is the fastest and most efficient trimmer for large cartridges from the 338 Lapua Magnum to the giant 50 BMG. Based on the original WFT
, the Big Boy trimmer chucks into a drill or drill press allowing quick work on case trimming. Referencing off the shoulder, this trimmer uses razor sharp high-speed cutters and sealed ball bearings to produce an extremely smooth cut. The Big Boy World's Finest Trimmer utilizes trim chambers for each cartridge/cartridge family. This allows you to purchase only one trimmer and multiple, less expensive trim chambers to do different cartridges.

Requires the use of a trim chamber (not included) for each cartridge or cartridge family.
Most drill chucks have a little wobble to them, but with experimentation reloaders can find the sweet spot where the WFT runs perfectly true and can be spun at higher RPM's
To get consistent results, brass should be resized before being trimmed as the expander ball on resizing dies will cause case necks to stretch giving inconsistent case lengths.
