.277 Wolverine "WCT" - World's Cheapest Trimmer
Same concept as the other drum-versions. Just like them, loosen the set screw to adjust trim length by moving the end mill, WLV case fits nicely in the cartridge-specific chamber body of the trimmer. Less than half the price of other popular variations. Trim body is made of a resin/polymer, virtually indestructible. Made by Holub Machine, the WCT - "World's Cheapest Trimmer" is a great value.
