I hesitate to opine: I don't like controversy, but here goes.
I only have 1 Lee die set :.270 collet die & it works well.
Every rifle die set otherwise (different brands) has a Redding neck die. In the past I've owned Redding bushing type dies & have used Redding bushings in Wilson hand dies with complete satisfaction.
However: for handgun loading I'd never, ever recommend Redding dies if you plan to use cast boolits. Redding makes great stuff, but they have a fantastic misunderstanding of handgun loading with cast boolits. Their stuff is so good that they can't believe there is a problem. It's like dealing with someone that speaks another language. The problem is the person with the problem......surely it can't be the Redding product.
I load cast boolits exclusively for handguns & use Dillon dies (except for that 1 Redding set (now altered). The Dillon feature of different seating shapes & ease of cleaning is hard to beat + you could buy 2 Dillon sets for the price of the Redding (also no hassle if you have a problem).
I didn't intend to step on any toes.
