I had a Redding morcometer trimmer for years that I sold because it was literally a 'pain in the hand', after a number of cases, cranking the handle got, shall we say, tedious anr it was hard to hold case length across a number of cases because the inherent deflection on the spindle/chuck arrangement imparted inaccuracy from one case to another, so it went 'down the road'.
I looked at various case trimmers, keep in mind that when I trim, or should I say when the cases get trimmed (because I like to relegate that job to someone else), it's usually 1000 cases or better at a crack, a lot of trimming....
I wanted a case trimmer that one, had an easily replaceable cutter (most case trimmers use a proprietary (expensive cutter), delivered repeatable accuracy across a number of cases (the Redding didn't without serious fiddling on my part and having another of the group trim made it even worse) and wasn't a 'pain in the palm after a large number of cases.
I stumbled on the WFT in a review on the web and subesquently ordered one direct from Dale at Little Crow.
It (WFT) workes quite well with a caveat or two. I don't use the drill motor method. I chuck mine in a collet on one of my engine lathes, I replaced the 2 flute end mil with a 4 flute Micrograin Tungsten Carbide endmill and I bought (from Dale) the necessary and required for my reloading, inserts. I also machined a number of inserts from Delrin (plastic) to point ballistic tipped pills with. I tend to load Sierra Ballistic tipped pills and Sierra's tip(s) are notorious for deforming. The plastic inserts machined to the bullet ogive allow me to consistently tip, tipped pills for uniform COAL.
The WFT is very consistent far as holding case dimension across any number of trimmings. Typically, I can hold 0.005 across any number of cases and so can my heplers, thats important to me. I learned quickly that it's better to feed the case into the trimmer with 2 hands, one feeding the case and one rotating it against the cutter.
It's also a minor PITA to set your cartridge cut length. I use a dummy, already sized to length cartridge and set the end mill against that to set the cut depth, unlike lathe type trimmers where you can'dial' the length pretty close, the WFT has no length indicators.
Finally, because the WFT uses a chamber cut insert to to loacate the cartridge for cutting (using the shoulder of a bottleneck cartridge), it's imparative the you keep the insert clean from cut chips. I use an air hose to blow it out.
All in all, it works quite well for my uses and even with 4 extra inserts, it was about half the price of the Redding.
I better add that you can't trim a straight walled case with a WFT but then, you can't do it with any trimmer on the market (that I know of) anyway. I shoot a bunch a 44's, 45 Colts and 357's and I've never trimed a straight wall case because they don't grow. If anything, they shrink.
