Anyone have one of the ones from Little Crow?
Yes, I have a couple of the WFT and like them a lot. At first I thought they were a bit expensive since each one was limited to cases of the same "family", but I bought one each for .223 and .30-06 type cases and they have proven to be well worth the money in time and effort saved. Cases come out very uniform in length and it only takes 2-3 seconds each. There is some small art to it since you should use a similar pressure when feeding in the case mouth but you quickly develop a rhythm and feel for it.
The latest generation has replaceable inserts for each case type and if starting today that's the way I'd go. In fact I might still get one of those.
Still have a 35 year old Lyman electric trimmer and pilots for those one-off case types and it works as well as it ever did but it feels really slow in comparison to the WFT.
