Re: problems reloading for 40 S&W?
I have RCBS, Hornady, Redding, Forester, Dillon, and Lee dies. The Lee dies are the only ones that have rusted on me over a 20 year period.
My opinion, and others vocally disagree, is that Lee uses inferior materials in their products. They make the design and choose the materials so that the products meets a price and offers no extended life. The rest of the industry tends to over design their products and use superior or more than adequate materials, for the most part.
Again, that's my opinion and you can take it or leave it. When I buy new die sets I choose RCBS. But I do buy the Lee Factory Crimp dies and sometimes buy the Collet Neck Sizing dies, even though they both have given me trouble with the parts galling against each other, requiring repairs by stoning the working surfaces, repeatedly. Those two Lee product design concepts are revolutionary and the concepts work amazingly well, regardless that they suffer durability problems for me.
So you choose.... price or durability, or so my opinion goes.
