Ivan covered the question perfectly. RCBS is my go-to supplier. Their dies are good and their customer service is impeccable. The few times I've used their customer service, I was extremely pleased. They earned my repeat business. Sure, Lee is cheaper, but I'll direct cost isn't the whole picture. As for Hornady, they should stick to bullets. I purchased a few Hornady die sets for some oddball calibers that others didn't stock. What a poor excuse for a set of dies.

Now I know the OP asked about 44 handgun cartridges, but for making itty bitty bugholes with a primo rifle, my money is on L.E. Wilson. The dies are beautifully constructed and look like jewels. And they work!
