I'm with 405 . I have a mixture of colors on my bench(It used to be only green),I've tried all of them amd they all do the same thing for the most part,but I have only had problems with one die and it was Lee(the very first Lee that I bought because so many people stood up for them).I looked up inside the die and the surface that sizes the neck was rough and not polished very good.
Now that said die would not size the rifle cases that I bought it for, it took quite an amount of pressure to use,and the sound coming from it told me what was going on. I tried every lube I had plus went into the garage and tried several thick oils, finally seized one(I knew it would happen).I pressed it out and called Lee. The guy I talked to said "if you want the die to work use Lee lube",that is arrogent . He wouldn't even listen to me when I told him the surface was not right or that the other case lubes I used(Imperial sizing wax and RCBS case lube) worked fine for everything else so why wouldn't it work on their die. That put a sour taste in my mouth for that company.
I took that die set back to the lgs that I bought it from and told him the story(he was a Lee fan of sorts),he took the die out , put it in his press out back and promply seized a case using LEE lube! He then traded even up for a RCBS set and I had the 100 cases sized in 20 min,no issues. The ironic part is that I bought the Lee because they were "cheaper" and I don't reload that caliber much so I wanted to save money. After $25.00 in extra gas I ended up with one of the brands that I normally get. Didn't save anything.
Now yes they(Lee) do make some good stuff and it works as good as the "others" but just looking at past threads here and on other forums it is clear what brand has the most issues. That is the price difference.
