I just started reloading last year and bought the Lee Breech lock Challenger kit, and lee dies for my .204 and 7x57, i have the .204 shooting 3 shot clover groups and the 7x57 is getting close. I added a powder trickler, trimmer and a few other odds and ends from different manufactures, i now have red stuff, green stuff and orange. i do like the lee dies better than my RCBS dies.
