I'm hesitant to respond, but the inference that if someone has a problem, they are wrong... well that's just not the reality of the situation.
I've sent dozens of customers to whidden. Once upon a time they were the only game in town for truly custom wildcat dies. I have more than a couple sets.
I'd say my customer feedback on satisfaction sits at about 50%-60% on the first time through... and sometimes it's taken 3 dies before they get it right. I'll mention them to people as an option, which is probably better than most options presently... but still leaves a LOT of room for improvement. My most recent die set is a 20-223AI... which I sent my own resize reamer to have cut. That die scars the necks on my brass... badly. I'll have to go in there and clean it up with some abrasive... just as I've had to do many times in the past. I've yet to inspect my reamer to see what damage, if any, was caused during the cut.
The insinuation made here that anyone having problems with whidden dies is somehow incompetent... is ridiculous, unwarranted, and not based in the facts. Most people are working on a sample size of one or two. Some of us have a large body of experience with whidden, spanning quite a lot of years. They've had problems. They've been informed of the problems. The problems apparently still exist. Which is too bad.
Short Action Customs dies look to be the next logical step forward.
