Ever since I started making my own .300 brass out of .223 I have been looking for something better than my Lyman manual trimmer. I looked around online and ran across the "WFT" or Worlds Finest Trimmer from Little Crow Gunworks. I paid $70.00 for it and got it in the mail this afternoon. After running 50 rounds thru it I am completely sold on this thing. It is lightning fast and gets the brass very close +- .001. As I stated I have only ran 50 rounds thru it so I don't have any long term feedback, but so far this thing is incredible. For those of you making your own .300 for your Blackouts, this thing is the bee's knees.
