Great reloaded rifle ammunition is about many things, but none are more important than case prep. If your brass isn’t sized and prepped correctly, you can’t expect to get reliable performance or precision from your loaded ammunition. Fortunately, there are many great tools that can help minimize the work required for brass prep, and help to ensure optimal results. One such tool is the World’s Finest Trimmer (WFT) from Little Crow Gunworks!
WFT: Original Edition
As you saw in the video, this trimmer is compact, easy to setup, easy to use, and it’s also affordable! Here are two of my WFT trimmers, one for .223 Remington (left), and one for .308 Winchester (right).
I like the fact that these trimmers (pictured above) both use a standard 3/8″ 4-flute endmill, the kind you’d use in a milling machine (I have LOTS of endmills laying around, some inherited from Grandpa!). They should trim thousands and thousands of cases before becoming dull, and if they ever do become dull, I can either swap out a new endmill, or have these sharpened. I could even upgrade to carbide if I felt the need!
The endmill is secured by two allen setscrews (1/8″ allen key required). That makes it super-easy to adjust trim length. The easiest way is what I demonstrated in the video above:
- Loosen the set screws
- Pull the endmill out ~1/8″
- Insert a piece of brass that’s trimmed to the length you want to set the trimmer to into the opening opposite the endmill
- Lower the endmill against the brass with gentle pressure
- Tighten the set screws while holding gentle pressure down on the endmill
- Check trim length by trimming a piece of brass, adjust height as needed
It only takes a minute if that to make these adjustments!
WFT: Big Boy Edition
So what if you want to trim something *BIG* like 50 BMG brass? Well, Little Crow Gunworks has you covered! The WFT Big Boy Edition is a larger version of the WFT Original trimmer, but mega-sized, and also incorporating an insert system that makes it easy to use the same trimming head with multiple calibers.
Inserts are available for most popular large-caliber rifle chamberings including .338 Lapua, .375 H&H, .378 Weatherby, .408 Cheytac, .416 Barrett, .450 Rigby, 50 BMG, and many others! I’ll be showing the WFT Big Boy later when I start my series on 50 BMG.
WFT2: World’s Finest Trimmer 2
The WFT2 is an updated version of the WFT Original that employs inserts much like those used by the WFT Big Boy! The body costs the same as the WFT Original, and you buy inserts for each cartridge you want to trim cases for. Pretty neat!
So far, I’m really liking the way the WFT trimer is working, I’ve trimmed quite a few .308 cases already with mine. Stay tuned for more WFT content here on Ultimate Reloader! Are you using WFT trimmers? Please leave a comment to share your experiences!
