No fault of Grafs, But Lee Precision should rethink this one.
By John R. on Aug 23, 2025Sadly, Lee is making more and more of their products with added safety measures, and these interfere with smooth usage. But this system is a joke. I cannot say I am a fan of the breech lock collars as well and prefer the swapping out of the casehead. If I try another Lee it will be the 6 station model as it does appear to have an auto priming system similar to the 1000. I have a Dillon 650 fully set up, but like to use a stand alone press for some other calibers and the Lee price point is less than converting the Dillon.
No fault by Grafs, they get 5 Stars. Delivery was prompt and best price I could find on any Lee products.
