Hello. Bill,the Pro 2000 is an outstanding machine. I loaded for several years on both a Dillon 550 and 650, but for a number of reasons I consider the 2000 superior to the Dillons and have let them go down the road. The Dillons are excellent,(the 650 ia a very fast machine,to boot); they have an unmatched following, and have a huge weight advantage over the 2000 which is why I think that they remain the pre-eminent choice of competitive shooters,(on the road). They work! However, as always, the devil is in the details!!! Study press design and features thoroughly and your choice will become easier. This shooter,like the NRA technical staff, selected and uses the 2000.
A few of my personal "likes" are as follows:
Cast iron vice aluminum frame and (critical)toggle assembly ; ease of use and caliber conversions; powder dispensing,(design, accuracy and repeatability) ; case retention and priming,(both strip and tube).
I've loaded for fifty years and I consider the Pro 2000, Redding turret and Rockchucker,respectively and by category, to be the best machines ever made.
Enjoy your quest!
Best,
Bill C
