Have 5-6 of the original style wft's from before they came out with the bushing style. They will hold .001 with consistent operation & not rushing things. With mixed brass & a bit hurried operation it will hold .002 pretty consistent.
The only disadvantage to the bushing style would be having to reset it all the time. Mine don't really need adjusted ever. You can try other fairly similar necked cases in them to. For example I use my 30-06/270 wft to trim our 30-30 brass(requires adjustment though). The 308 wft will do x39. Basically, if the cases were sized in the same die, the neck is about the same length, & the same caliber it should work & be consistent. Works very well & nothing I know of is faster for the money.
No reason to be full length sizing & trimming all the time unless needed. Its not a fun job.
Got mine mounted on a temporary bench with some plumbers strap.
I put a few sharpie marks around the bushing to tell when it stops.
Need to find a method as fast & consistent for the straightwall mag cases.
