Whidden’s meplat trimming system ensures consistent shaping and sizing of bullet tips to eliminate one variable that can compromise accuracy. It works in your Wilson Case Trimmer, so there’s no need to purchase an additional, dedicated hand crank assembly. The bullet is retained in precise alignment with the Wilson tool’s cutting head between a caliber-specific bullet holder and a cap that fits over the case trimmer’s length stop, so every bullet is trimmed to the same length. The holder keeps the bullet dead straight, so the tip will not get trimmed at a random angle that leaves it out-of-balance. Trimmer kit, bullet holders, and Wilson case trimmer must be purchased separately.
